Color Picker

We are always complaining about color pickers that are available for jQuery. So I have designed a very basic color picker and am hoping the dribbblers out there can help me improve it.

If you have any improvements to make to this panel (or the other two you can see in the attached png) rebound this shot.

At the end we'll make it into a fully functional jQuery plugin and provide it for anyone to use.
