How color changes in a room. Every wall in this room is painted the same shade of gray, but look at the differences caused by the angles and placement in the room. Color also looks different under different circumstances: The day progresses and the natural light in the room changes, seasons change, a couple candles at night or all recessed lighting on full blast changes the appearance. It is worth the expense to paint samples on multiple walls before you commit to a color. The lighting in the room should be finalized too — don't look at samples with temporary bulbs hanging from pigtail lamp holders. And be sure to check the color at different times of day.

A few ways to affect color through lighting:
  • To warm up a room's color: Look for a bulb with a temperature close to 2,700 Kelvin. Halogens are a good choice, but all types of bulbs are available in warmer ratings.
  • To cool down a room's color: Look for a bulb with a temperature close to 4,000 Kelvin. Standard fluorescents will generally cool down a room, but check the numbers.
  • To most accurately replicate natural daylight: Midday sunlight is around 5,000 to 6,000 Kelvin, but keep in mind that this is very cool light — contrary to what you might expect.

Note that the chandelier in this room is not on. Combine this with the fact that colors look different on different computer monitors, and what you see in the photograph is at best close to what the room looks like in person.

Tips for choosing a lightbulb. You've probably noticed that there are a lot of options these days when it come to shopping for lightbulbs. Though most of us have a sense of what to expect from a 40-watt incandescent bulb, watts are no longer a good way to describe a bulb's light output, now that different technologies use different amounts of power to produce the same light.

Compare lumens to see how bright a bulb is, and if you want to know how warm or cool the light produced will be, look for the kelvin rating. For the warm light traditionally produced by incandescent bulbs, look for close to 2,700 Kelvin. Most of the old fluorescent tubes you're familiar with are around 4,000 Kelvin. Fluorescents come in many varieties these days, from warm to cool, from traditional tubes to compact fluorescents (CFLs), all in many interesting shapes. Each will have its own effect on the colors in your house.

If you're concerned that the government has outlawed your favorite lightbulbs, plunging you into a confusing world of ugly-looking lightbulbs that give off weird light, have no fear. The only thing that has been outlawed is selling lightbulbs that heat your house more than light it. The old incandescent bulbs converted only 10 percent of the electricity used into light; the rest became heat. Ever hear of an Easy-Bake Oven?

Incandescent light is still available but in a more efficient package. Look for a halogen bulb like the one lighting this chandelier. These bulbs look the same as traditional bulbs, but with the filament encased in gas, they are able to produce light like a 100-watt incandescent bulb with only 72 watts.

Use light to your advantage. The light source you choose affects how colors appear in a room, but so does the way you use the light. On this project, the gold leaf wall is washed with light from a bright LED strip. This combination gives off a warm glow. Light-emitting diodes (LEDs) are the longest-lasting bulbs out there, and they cost the least to operate. They have a greater up-front cost, though. Don't be surprised to pay $20 for an LED. Though the lifetime savings are worth the investment, if you don't like the quality of the light, it's all for naught.

Go to a lighting showroom where you can see different bulbs in action, or buy one and use it in the basement or garage if you don't like the color. If you like the yellowish light cast by a traditional incandescent, try the Philips Ambient LED. At 8 watts, it uses 80 percent less electricity than an incandescent 40-watt bulb.
by McClellan Architects
Adjust bulb color with fixtures. If the color of light produced by a bulb isn't quite to your liking, you can tweak it by picking a fixture shade that changes the light, like this glass shade from Schoolhouse Electric. But know that an enclosed shade on a fixture that hangs upside down like this has limited bulb options. LED bulbs will not last as long if they're exposed to the heat buildup in an enclosed shade. CFLs don't like to hang upside down — they will work and still generally last longer than an incandescent, but you won't get the full predicted life out of them.

This cool modern chandelier has exposed bulbs that would look great with some of the interesting-looking LED bulbs that are out there now. If your fixture is on a dimmer, keep in mind that while the color produced by the LED at full strength will match that of its equivalent incandescent, when dimmed the incandescent will get much warmer in tone, while the LED will just dim and the color will stay pretty consistent.

Get help figuring out a lighting plan. Due to all of these factors, it can really pay off to have a designer help you with a lighting plan. Someone with knowledge about the lighting options will be able to maxmize energy efficiency and help you get the color in the room just right.

Fluorescent tubes are placed behind the mirrors in this room. Incandescent recessed lighting and LED accents make for an interesting mix.

Using natural light. We've spent a lot of time talking about artificial light, but controlling and monitoring the natural light a room gets is also critical to selecting the right colors. Large windows are expensive and require blinds or curtains for privacy. For diffusing light on a large scale, consider Kalwall panels. These fiberglass panels are gaining in popularity in residential projects and can flood a room with light without the glare. Of course, just as with any source of natural light, colors will look different throughout the day, so don't pick a color you love at 10 in the morning, only to find it looks drab and dreary when you come home from work.

Velux Sun Tunnel Skylight [ Link ]
Light from a skylight can be harsh, creating a spotlight effect and bringing as much heat into the house as light. Skylights also often require structural alterations to roof framing, and structural changes are never cheap. Instead of a skylight, consider a tubular daylighting device, shown here in cross section. Like Kalwall panels, the device fills a room with diffuse natural light. Though a 5,000- to 6,000-Kelvin bulb will supposedly reproduce natural light, there's nothing like the real thing. Even though the new bulbs out there use a lot less power than those Edison bulbs, there's no beating free light.

Dirt Digger I love this idea book! Hopefully, every houzz user will read it and come to understand how light changes and affects everything, including color!

aeykelbo Thanks for a great article Kenny... It puts me in mind of the time I decided to take a risk on yellow. I spent time trying to find the exact shade I liked and then I bought small amounts of the top contenders and did patches with several coats. Finally, I got just what I wanted, painted up the room.... and the sun went down. The moment I turned on the light (which I never thought to do when while testing), that lovely shade turned to a horrendous traffic yellow. Whoops.

In horror and despair, I immediately painted over it again, but if I would have seen this ideabook, maybe I could have rescued it through the lighting. I hope to never have another yellow fiasco, but if I do, at least now I know how to choose the right bulb! This kind of useful technical information can never go amiss on Houzz.

klopty I have done a lot of renting up until now and so I've had little chance to colour my walls or choose lighting. l'm really looking forward to customising these things in the future. Which is why your article had a big impact on me: full of simple yet profound advice, which will steer me away from some rookie mistakes when I am finally let loose on some walls! And someone has finally explained the confusing bulbs! Thanks!!

PaintColorHelp.com Dallas This is one of the most helpful articles I've ever read on Houzz. Good job synthesizing what can be a complex subject. I constantly remind my clients to check their colors under the same lightbulbs they'll ultimately use. Changing bulbs after a room is painted is a good way to ruin all your color planning.

appytrails Wow! What a great article!! I am one of those totally confused people who stand in front of the bulb section at the hardware store not knowing what to choose. Not any more, thanks to you, Kenny.
I plan to print this out, make notes, and keep it as a reference. It's the "Everything you always wanted to know about lighting but was too confused to ask" manual.

minimumjoe DEAR Mr. Grono! Where the heck was your ideabook when wife and I were setting up this house! Sheesh. We did figure out most of what you say, but it took months of changing this and changing that.

We like a modern/contemporary pallet in a house that doesn't get a lot of direct daylight ... here's what we ended up with.

CFL and LED bulbs throughout. (Gradually move to all LED.) All in 5000-6000 K. It's not for everyone, but we love what it does for our grays and whites and walnut flooring. We didn't want yellows or browns and the light clarity helps with all of our ideas.

Cost for bulbs (so far): a bit over $1000. I'll let you know when I have to replace one in between 35 - 45 years.

Thanks for a good article. Now bookmarked; we have to upgrade everything BUT lighting in the kitchen and two baths, so I'll save myself all kinds of time by using it then.

I should add: the big box stores carry very little other than 2700K and a few 3000K bulbs. We had to order ours online.

cookingistherapy We have a solatube which is compable to the velux suntunnel. We put it in a windowless bathroom. It completely lights the space during the day and on bright moon nights acts as a nightlight. It was about $650 including installation and truly is the best money we spent on the house to date.

mrsben Very informative article Kenny and have printed it off.

Not to dispute your advice; just recently in one of our leading newspapers in our City the heading read "Mercury bulbs pose a growing threat". (I live in Canada.) In a nutshell the topic targeted 'lack of storage or manage of mercury waste' and went on to mention that without proper legislation and control over so-called compact fluouescent lamps or CFLs, 'they and the mercury they contain in many cases will end up in land fills where their harmful mercury can get into the water', etc. An example given was; mercury contained in a typical thermoter can contaminate five Olympic-size simming pools to toxic levels'.

With that said; from my own experience while working in close proximity to a hard-wire ceiling fixture that was equipped with three CF*s I quickly discovered that they triggered vicious head-aches (that came as quickly as they went when out of range of them) giving me reason in event if I were personally to use even one it would not be put in a reading lamp nor worse yet in a child's room.

jogrant We've had one of these in our hall bath (that has no window) the 7 years and have loved it. Many guest have tried to "turn off the light" and tell us they can't find the right switch! Our roof is slopped and there are what our contractor described as "attic support boards every which way" but with the flexibility of the tube if was easily installed. Ours has a light bulb inside the tube so even on cloudy days and at night there's seemingly outside light coming through. I wish we had more.....,maybe some day!

Diana Bier Interiors, LLC I totally agree with mrsben regarding those CFL bulbs. But who on earth couldn't foresee that the mercury issue would have become a problem? It was so obvious to anyone with a brain when those bulbs first came out. As soon as I read that if you broke one in your house you had to open all the windows, stop breathing, and call in a hazmat team to dispose of it. But of course our legislators in their infinite wisdom never thought of this when passing the law to save the planet by ruining it. Add that to the fact that the light from the CFL bulbs makes you look green and ill, I have never put one in my home.

I was hoarding incandescent bulbs until I stopped by my local lighting store and found out that the halogen bulbs are the preferred alternative. They give off wonderful natural light and little heat. They are fairly expensive, but I was assured that they will outlast the old incandescents. Time will tell.

ans275 One thing to note when using LED bulbs and dimmers is that at certain points of the dimming range, depending on the bulb and dimmer switch, the bulbs will flicker or pulsate.

Sarah Miller Very helpful ideabook. The electrician installed recessed LED lights throughout our new construction and I CAN'T tolerate the light they give off. Too cool and bright. I can't justify spending the money on replacements throughout the house --am wondering if dimmers would do the trick?

austennut Thank you so much for this ideabook. I usually seem to have a pretty good handle on color, but I was getting some very bad advice from lighting people where I live (both at a real lighting store and at the lighting specialists from big box home improvement stores). I had (have) a green color that I love during the day, but at night with the lights on it looks fluorescent green. They were telling me to get daylight bulbs at 5000 kelvin, but my paint kept looking fluorescent. Now, I realize I probably should have gone with 2700 to warm the green up. This is, of course, after several replacements of light bulbs & fixtures. I've bookmarked this ideabook. Thanks so much for putting it together!

nclandau Great article. This is the most straightforward article I've seen on the topic. Thank you for helping me see the light. (sorry, couldn't resist).

minimumjoe When I bragged about how much I like my 5000K LEDs I should have said "in my opinion." It works great for me w/grays, whites, and pops of bright colors. BUT I wouldn't want it in a room with browns or yellows, or a color that has a yellow tint in it. If you're goal is "warm," then 2700 K LEDs are available and do a nice job.

A lighting designer (for retail stores) said that in a home lighting should be handled by thinking of it as an enhancement for color (if you pick the right lighting). It helps me to think of it that way.

I sure do agree with the comments on the quality of light from CFLs! We tried to delay some of the expense of LED lighting by using CFLs in a good number of lights. Flicker, glare, general ugliness are all on the menu when you turn those on, especially if you've bought the "cooler" kelvin bulbs, i.e., 4500K and up.

The earlier fear over the mercury contamination levels during breakage has died down to practical levels ... but breaking a CFL is still not a good thing. And the end of life of the bulb should be handled via recycling; Lowes and Home Depot stores, among many others, have containers which are then sent for recycling. Just don't throw the bulbs in the trash.

One clarification: the mercury in an old thermometer is many times greater than the tiny amount in a CFL bulb.

wantsideas That first picture says it all about lighting. It looks like 3 different shades of paint on the walls or 4 if you count the ceiling.

Pangaea Interior Design, Portland, OR For almost every interior design client I work with, lighting is one of the very first things we address. No point choosing paint colors until we get rid of the CFL's in their recessed can lights. Halogen and xenon are my preferred choices for interiors, but LED is improving and I've specified it a number of time lately. It is especially great since we can conceal the super thin strips in display cabinets or around medicine cabinets for some accent lighting. Great explanations on color temperature.

Writing interior designers to ask them what paint color is in the picture is such a waste of time. NOT going to look the same in your house. It's great to see those pictures and use them as a general point of inspiration, but lighting, photography and printing or computer monitors all alter the way the colors look. I've even spoken with people who saw a paint color in a friend's house in person -- loved it -- and then painted it in their own house only to be very disappointed because it just didn't look the same. And they were utterly mystified as to why. This post does a great job of explaining how lighting alters colors. Add that to the way the other colors and finishes in your house affect paint colors and you realize you just need to address your lighting first, then choose colors by bringing them in to your home to see how they look there. A lighting consultant and/or color consultant are both a great idea if you need help.

Diana Bier Interiors, LLC That may be, minimumjoe, but I'd rather keep ALL mercury out of my home and my body. There are plenty of alternatives to CFLs and I can't see any reason to use them.

Creative Design by Lauran LLC This is an excellent posting about light and how we see it depending on bulbs, natural light, etc.! I am still learning (as many of us) about the new choices in bulbs and will try several of the choices you mention as well as comments above. Frustrating when a client refuses to put two coats of paint in a LARGE swatch on the wall and live with it for several days. Inevitably, they don't like it because they haven't even given it a chance!! Color consultations can be a tricky thing! Thanks for your information here.

patscats2 I think this is the number one mistake people make in choosing a color, not considering the light in the room. I know, been there, done that, $100 worth of paint later!!

I painted a hall a nice green, I thought. Until that night when I turned the overhead light on and it was like standing in a neon bubble!! It was so glaring and horrible I had to repaint the next day. Freaked me out so much I repainted it off white. I thought no way was I trying to get bold in a hall again.

Then there's the time I was trying to find the perfect taupe, so I came home and went to the darkest corner of the room and wondered why the paint looked so dark!!

My yellow experience was a nightmare until the guy at BM gave me Rich Creme and it turned out to be the palest and most pleasing of yellows that wasn't even a yellow. When we built this house that's the color I chose for my great room/dining room, laundry and pantry. It's a wonderful neutral and everything goes with because it has no undertones and whatever light hits it, it is beautiful.

Outdoor Furniture Plus Great article. I agree that the proper lighting is super important. So many folks overlook it. We recently purchased a new home and the lighting is just awful so we are gradually converting fixtures to dimmers and the LEDs that you talk about. Then we need to add more lighting in areas like the kitchen.

It's amazing how up until recently, lighting was such an after-thought and now homeowners and designers are realizing the importance of it.

Like a previous post, we have been purchasing our bulbs online. Here is where we found a great selection. http://www.lightbulbmarket.com/endura-led-a19-(a55)-light-bulbs

frenchdecor Great article. One thing was omitted about CFL bulb that it is efficient for long term light's on use (8 hours or so) which is more suitable for commercial spaces and offices. Professional, supposedly knowledgeable, electricians were replacing them and all, not unaware folks. As in homes we turn on and off lights very often only for short time CFL bulbs have much less life time than marketing claims. And of course it takes some time to get bright light in the room.
I hope next time we'll read about recessed lights chose, effectiveness and it's insulation.
