Recently I played some korean defense map (can't remember name right now) and there were buildings/units with some really strange colors. For instance, I recall the Protoss Fleet Beacon icon being completely blue, there was a marine whose icon was more like a zerg unit, with green surrounding and gradient yellow towards the center. There were some other weird things, like pieces of the icon missing or in completely unusual tones.
My question is, how can I get those different colors on units icons? Do I need some special editor?
If I can find a screenshot of an ingame scene I will post it later.
Thanks in advance for any help.
