Allow selecting the color of stars for previously bought donation levels

[Trenten]

Basically, for example, if a player has aether, they should have the ability to select star colors from previous donation levels, such as gold for wood, stone, iron, and diamond, or purple for obsidian, and red for nether, possibly from something on the control panel?

Perhaps this could also be done with the new system too?

Just to clarify I mean being able to change the color to a color below that level
