At the same time that I've been researching upcoming color trends for the Trendy Crochet class, color came up in the International Freeform yahoo group. This summer I just want to play with colors. I can't name a favorite color because of how they change in combination with others. Below are my favorite links.
Colorcube has lots of color games. My favorite is "Color Scrambles" because I love competing with myself to distinguish subtle shades. See also the articles and screensavers.
Colorjack is great for sophisticated color combinations. Many interesting options.
Wellstyled has a color wheel that is so well designed that it seemed simplistic to me at first. Then I looked closer and saw the refinements possible. Nicely designed, concise. I learned what my color combining biases are.
Colr.org uses actual random Flickr images (or others images of your choice) for real-life color schemes. It took me awhile to figure it out. Includes the ability to tag colors and if I understand correctly, the tags are communal.
Check out Lollygirl's Project Spectrum. It's not just for knitters anymore.
Lines and Colors blog has a pretty cool discussion of the color wheel and its development.
I bookmarked this list of color names because I learned such things as, I've had heliotrope (not neon yellow), olivine (not acid olive-green), and puce (not dirty caramel-chartreuse) wrong all my life! And, that I'm probably not the only one confused by "indigo" which sometimes appears as a deep herby edgy teal, and other times as a vivid violet. Check out all of the lavenders. How many people know what "zinnwaldite" looks like? Or Mountbatten pink??
And here's Rosebud, Queen of the Couch, circa 1999 (full name Rosebud Fu Fu Shen). If she could speak: "We both know that I'm not supposed to be on the couch, but I was just about to take a delicious nap, so you could waive that rule just once, right? I won't make a regular practice of it."
Rosebud was the most beautiful dog I ever had and probably the most intelligent. Also the closest thing to a tawny pet lion.
