As some of you know, I’m colorblind. A colorblind ex-graphic designer to be precise.
I didn’t quit because of my problem identifying most colors —I now actually study car design which is way more critical when it comes to chosing colors— but I inevitably have to start any color composition by picking named colors off Corel Draw’s default palette. Even reading “Light Blue Green” on the status bar makes me feel confident it is indeed a light greenish blue or something like that. Picking colors from a photo or a website is another story, and I have to rely in the pseudoscience of RGB hexadecimal code to decode what a color might actually be.

But today we have tools like Name That Color, a genial (free, open-source) web tool for everybody to check the actual real name of any color and thus the identity it’s been hiding, or select one of the 1500+ preset color names in order to get its RGB code (or just to see how the heck the color wisteria looks like).
Also invaluable for many can be the several color palette generators that generate 5-20 colors based on any photograph, either a url or uploaded. For even more random inspiration, colourlovers.com has tons of custom palettes by users, but if you really want to combine colors yourself, you may want to read some advice.
Now if only all the good brands of markers put actual names of colors on the labels, and not only the bad ones.
