color

Very nice site. I've used colr.org in the past, which does basically the same thing. I have to say, though, the UI on colorapi.com is much better. Good job! This site is bookmarked for use on my next web design project.

One feature request: the ability to upload images directly to colorapi.com.

Uploading images directly would allow designers to build a color palette to match a corporate logo, use the same color palettes as movies (by uploading images from http://moviebarcode.tumblr.com/ ), etc.
