Rio Brewster here's the drawing. colors are a little brighter in the drawing, but not much.

Susan Jablon Mosaics We have a grout called Starry Night, but it is probably darker than you're looking for. The image below on the left is it used in a blend with similar colors to yours, to give you an idea. You can try out all of our grout colors in our Mosaic Designer, http://www.susanjablon.com/designer/mosaic-designer.html It's an awesome tool to look at layouts, color combinations, and grout to really make the tile pop.

Something else to consider is using paint or dye to tint white grout. The image on the right is a mosaic one of our students made. We mixed a few drops of a high quality acrylic paint in white grout to get the blue and yellow colors. Using paint usually results in a pale hue, especially if the paint is a cheap craft paint, which is probably an easy solution for you without spending a lot of money! We have also used RIT dye (the clothing dye), which results in pretty much the same color grout as the dye, but it's probably better for richer/bolder colors.

frances54 I was at the north Austin Flor & Decor last month looking for a light grey grout, they seem to have a pretty large selection and if I recall correctly, they had both a light blue and a kinda sea foam green. They're near 183 and Braker.

Rio Brewster They have a green called cool mint which is a little too green, but that's the current backup plan - other than like platinum or arctic ice.

Rio Brewster Thanks - the starry night is too dark. Caribbean blue is actually what I plan to use on the aqua pebble tiles on the floor. I'll talk to my contractor about using a bit of the wall color with white for a light tint - it's only 78 sf so they should be able to go in one batch.

Or I may just go with white and ask them to do epoxy.

Has anyone tried StarGlass with a mix of ceramic and glass? Aquamarine is a good color but I'm afraid if might be overkill for what is mostly white ceramic tile.
