Color Bar in bge?

Hi everyone, I am trying to make a system for changing hair color to the players exact reference. Would it be possible to make a color wheel where the player can drag the marker around and change the diffuse color of an object without effecting the texture? Alternatively could i use a color bar that when i drag the marker (only possible for it to be dragged sideways) the color changes? If neither of these is possible is there a simpler way to get the same amount of options and the same effect?
Thanks,

Yes it’s possible to do color wheel/slider.
The easiest would be three sliders (RGB), with clickable buttons to slide them. If you want to be able to click-drag or a color wheel, you’ll have to do more complex python coding.

As for changing the color, either use vertex color or object color
