Code:
color.new('ARCOS_BLUE', '.', color.ARCOS_BLUE, 0, 208, 200)
color.new('ERMOR_PURPLE', '.', color.ERMOR_PURPLE, 96, 52, 120)
color.new('EA_ULM_BLUE', '.', color.EA_ULM_BLUE, 80, 104, 136)
color.new('EA_CTIS_GREEN', '.', color.EA_CTIS_GREEN, 96, 144, 48)
I just loaded some of the flags from EricM's extracted flag graphics package into GIMP and selected a color from the graphic, then retrieved it's RGB code via the color dialog to obtain these. Hope it helps. I would do some more, but it is getting late here. (Great job so far Omni!)
