Well, lessee..
You say you don\'t want to go with purple/black. Are you talking about the flesh colors, or the garment colors?
??? Do you want to stick with a scheme that has some \'authenticity\'? Meaning, do you want to stick with a scheme that has been mentioned in descriptions of various game systems or literature? Or do you just want ideas for how to make your dark elves stand out? Fair warning, I have no idea what is \'authentic\' for the various gaming systems folks play. So my suggestions are all strictly aesthetic in nature.
You could look to the races of the world today for inspiration for the colors of flesh.. Dark could mean African, or it could mean Latin. Or it could be the color of their spirit and their flesh and hair could be northern European (i.e. blonde and pale-skinned). Can you imagine a Dark Elf with red hair and freckles?
If you\'re talking about clothing and accessory colors, you could take inspiration from the civilizations of the past. How about a Greek Dark Elf? or a Mongol? Or an Asian-inspired scheme with lots of red, gold, and black. A Dark Elf pretending to be something else would be interesting, like a Dark \"Wood Elf\"..
If you play one of the systems, consider whether you want to conform to their expected color schemes or not. Some may have rules about what folks can and can\'t do, I dunno. But if it\'s simply an aesthetic choice, you have huge flexibility. It doesn\'t have to be purple and black, it could be yellow and white.
Anyway, dunno if that helps or not. Have a good time with it, anyway.
