[0.1.0.7] RGB sliders don't change if you have it closed

Bug Report
1

I tried changing this table’s color with the RGB sliders closed, and it doesn’t change when you open it.

Also, the RGB values reset to 255 whenever you close the Color Window. Makes it really annoying to paint walls in the same color because I tend to forget the values and then I can’t check what it was.
