What exactly do you mean by "use their own customizable sliders"?

I think it should be easy enough to just use a simple color picker (the one with arrows around it) and just create 3 integer [Slider]s below it with onchanges to reflect in it. If that's sort of what you're looking for the potential exists for a [ColorDisplay] or something which doesn't have just options and is just the colored box.

Ye just the colored box

Can you give a sample of what you're actually planning on doing? Was it just changing the names?

Like that where the green is the color display

So is the ordering just your concern or do you want names? (RE: ordering, I do think the color should go first as generally the "overarching" item goes first like a mods section label)

The naming, but I also do prefer the color being below
