aandrews361 you want to create the look of sunlight without the actual light- I think I nice antique yellow would really make the room pop and look bigger. Hope this helps!

Carolyn C Try a lighter shade of the brown, your art work needs to be moved down and try something a bit larger with more colour if you want to bring some into the room. See the visual attached, Use a washable flat finish and good lighting so the room feels brighter.

Carolyn C Here's a more yellow gold colour so you can see the difference

Darzy How about antique white walls and a chocolate brown ceiling? Large artwork and blue accessories to go with the chair? Here is a white wall/brown ceiling. I think your ceilings are high enough for this look. Maybe have the door wall the chocolate color as well?

lovemypet I think Darzy's idea is great! Anntique white would make the room seem brighter and larger. The brown ceiling also would be perfect for the room, but not too dark of brown. The brown color on the wall shown is nice. Another nice brown shade is one that looks like a coffee color where you added a little bit of cream to it. Very similar to the one shown, just a tad bit lighter. Does that make sense? I don't think any other color besides antique white will make the room feel like there is sunshine or light in the room. Good luck

Manon Floreat I love the idea of antique white walls and a chocolate ceiling. Brilliant, Darzy! The antique white will have some yellow in it to brighten the space and the colored ceiling will be a great feature for a windowless room.

I'll add that really well thought out lighting and reflective elements (mirrors, glass,etc.) will help make up for the absence of windows.

olldbobbi Darzy, good job! You nailed it!....olldbob

anitajoyce Tan or beige will brighten the space.

Carolyn C Love the antique white Darcy. My original concern was that the space looks small and if the walls were too light the dark brown sofa and chair would just make everything seem smaller, hard to know without more info.

victorianbungalowranch Any possibitity of a skylihgt in there? The kind that fit between the trusses and don't open are the most economical. There are light tubes too, but they don't bring in that much light.
