What do colors above mobs mean?

Simply put, the levels denote how strong they are above your level.

Just bear in mind the same colored mob in one map will be a LOT tougher in another (Pando anyone?)


White 6+ levels below you
Light blue 4-5 levels below you
Dark blue 2-3 levels below you
Green --- SAME LEVEL AS YOU ---
Yellow 2-3 levels above you
Orange 4-5 levels above you
Red 6-7 levels above you
Purple 8-9 levels above you
Grey 10+ levels above you (NOTE...don't even bother fighting these as you won't get any Exp anyway if you manage to defeat it).
