Support RGB/HSL in color module

For example I want to use RGB values in the colors array, basic reason is so I can tweak these in color.css with RGBa and create a more cooler colored themes :)

Problem - while this does work, you cannot create a custom color scheme - this looks, initially, like a failing of Farbtastic, if this is so then we need to get rid of Farbtastic and use something that will use RGB, because RGB is the way of the future (RGBa is just to useful to ignore and not support).

Additionally I have tried simply using the RGB equivalent in colors.css, this works for the default color scheme but again you can't customize it, or even any other scheme, the hex to rgb conversion breaks down somewhere.

If I'm doing something wrong then please advise, I'd really really love to use RGB in color module.

Here's a sample of my scheme:

  'schemes' => array(
    'default' => array(
      'title' => t('Winter'),
      'colors' => array(
        'base' => '255,255,255',
        'link' => '5,118,229',
        'top' => '244,244,244',
        'bottom' => '251,251,251',

Basically what happens is the RGB values show up in the color picker fields, but you cannot change them, them, and the color does not actually show, the field is white with the RGB value (text) only. Please see the screenshot of farbtastic and the color form failing badly.
