The other day I was trying to describe what happens to RED when grey is added. I stumbled through several great websites as I did so.
Color Matters gives a brief overview of color theory that covers complementary and analogous colors. But spend some time with the various tabs across the top. This is a rich, deep resource of color information, including use of color in design, the meanings of different colors, the impact of lighting, and many other aspects.
Design Seeds — This site gives a new color scheme every day to inspire you. And if you’d like to customize your color scheme, try the palette search.
TryColors.com — Mix up colors in any proportions. This might not be very useful for quilters, but it certainly is entertaining.
Rapid Tables — Again, perhaps not useful for quilters, as it uses the “light” color theory rather than the pigment color theory. On the other hand, if you’re a blogger, you may enjoy playing with the colors that create your blog background.
MacMillan Dictionary — Do you need the right word for a specific color? You may find it here.
Words to Use — “Find creative ways to describe colors! These long lists of names for colors include words for red, yellow, blue and every color of the rainbow.”
This was a fun excursion into color. Do you have favorite color resources and inspirations? They could be books, bloggers, websites, or any other source. Let us know.

Great post for a colour lover! Thanks for the links they will be very useful.
You’re very welcome!
A couple of these are really cool, and useful for weavers, too! I wish I’d taken a course in color theory when I was in school.
I never took art classes, never had color theory. I think you can get a pretty good overview of it in books and sites available.
The only resource I know to contribute is Joen Wolfrom’s book Color Play. It’s helpful for dealing with analogous/complementary, etc. color schemes, and has beautiful quilt examples to drool over. I especially like the Design Seeds website you talk about, but am wondering if there’s a website for names to give paint colors. I’m planning to paint my kitchen in Pismo Dunes, which is a yellow with green in it. You’d never get that from its name. And my living room will soon be Tea Lights.
I have a couple of Joen Wolfrom books — great resources. But I don’t have this one. My guild might have it to borrow.
Pismo Dunes??? 😉
Sometimes I need to put the html code into a web site for a specific color. This site helps me get it right. http://www.w3schools.com/tags/ref_colorpicker.asp
It probably does not add anything to your choices of colors for fabrics and quilts. 🙂
I like this site. Thanks for sharing the link. xoxoxo
