Color picker

Hi all,

So what started this is that I asked Colin if Fluid was considering 
doing a color picker. I asked because if it was, then I was going to 
suggest it should allow colors options to be independently disabled, 
which in turn would allow foreground-and-background pickers to be built 
that could screen out poorly contrasted choices (see attached).

Such a control would consider the accessible of content likely to be 
created with the control (in addition to the accessibility of the 
control itself).

If anyone is interested in discussing this, please let me know.


PS: Actually, it seems to me that the ability to disable color options 
would just bring the picker in line with the family of radio-group 
controls, which color pickers would appear to be a member of.
