If any of you have ever struggled to come up with names for different colors, the Dolores Blog displays a wonderful color wheel complete with colors from a somewhat random sampling of people. The color wheel in itself is pretty interesting, but they also have a link to a page where you can search for colors. Just enter in "persian" to see what colors have persian in their label. Personally, I have always tended to plain labels like blue instead of cerulean. I'm not much of an artist though which probably makes a difference.
