Here's my color scheme. It's specialized for scouting, so base is green, signalling cubes that is free game for scouts. A cube that is already scouted is yellow (I kept it default because I like how satisfying the golden glow is). Anything that is scythe or voted on a bit is a shade of blue, symbolizing that it has been scythed. Anything that is most likely completed and therefore usually off-limits is red (enough votes, admin completed). Anything that is frozen by admins is black, and anything frozen by scythes is gray. Also, duplicates are pink, because they are kinda the odd one out.
