Colr.org is a website that allows you to play with colors and color schemes, create your own color schemes and much more.
I was visiting that site, and I've seen that it has an API. Hence I've integrated the twitter API with Colr.org API and created what I called TwitColr.
Why is it useful? Its just an easier why to see random color schemes and share it in Twitter. I might add some features to search colors by Tag. Example, give me colors with Cheese tag.
This is great for Designers to share colors with other designers via Twitter.
