Random Color Generator and Preview

I've created the online color viewer.

Everybody can preview any color using this base URL: http://karpolan.com/services/color/

Want to see a green color? Here it is: http://karpolan.com/services/color/008000/

A dark blue one? No problem: http://karpolan.com/services/color/000060/

Also, there is the Online Random Color Generator there.
