One thing I noticed that CO also lacks this feature (regardless of the fact that it has tons of feaetures in its UI that STO people have been begging for, for ages, like the ability to "Freeze" the character you are creating so it stops fidgeting, or the larger, more visible mouse pointer ... so on).
Some sort of text based label for the color would be a good idea to add to help colorblind players.
Lots of colors would be hard to label. There are many colors for some palettes, so maybe just a hue label? (Red, Orange, etc)
Any other ideas?
The short term solution would be to just show the Red, Green, Blue values of the boxes in a tooltip.
1) "192 64 0".
2) "221 109 91"
3) "255 190 164"
Later on, this could be extended to add the name of the color to the tooltip as well, if it matches a particular, named color.
