I want to change the one-colored picture of an actor using RGB color codes (ex.: 32, 54, 87)
First, when the key "0" is pressed down, you get asked which color codes you want to use. Then if you click on the actor the color should change, but it doesn't work.
Here are the codes for reference:

(BLACK ACTOR CODE):
