If you have a material that also has a color wheel next to it (like Sticker Panel) you can change the color of the material and the decorations placed on it will also become this color. You can even make Sticker Panel invisible, so it looks as if the decoration is placed on something else.

If you place the decorations on a material which's colour you can't change it will be the decorations default colour or white/greyish/black.

If you place those decorations on yourself it will become the same colour as your Popit Menu.
