Most color pickers used on the web today only support web colors. For some applications like a garment or a paint shop, each color code should reflect the color from the real world.
TCP (True Color Picker) uses GD library to provide color picking facility as many colors as in "Photoshop" color picker.

There is only one factor you have adjust, the "detail factor". It determines how many number of steps/blocks between each corner of the 256*256 picker box. Thus maximum is 256.
When it is set to 256, the total number of colors available is 256*256*256. Minimum setting should not less than 16. Optimum is 64.

You pick a color code using GD, you re-display it using GD. The "ColorElement" class can display any valid color codes (#000000 to #ffffff) in a variable size rectangle box.

Drawbacks
----------------

You can preload a color to TCP to show in "current" box, like Photoshop. But TCP cannot locate that color in the picker. TCP does not support CMYK color. 
They may come up in version 2.

ColorElement class does not support textures.

Tested on: Firefox 2 and IE 6.

Happy Picking!
