To help with target identification in the FMP mod, I've been cobbling together a mod to color-code aliens according to their ranks. It's a companion mod to FMP, because not everyone wants that kind of a visual giveaway. It's also a work in progress - not all races have been converted, and only the main battlescape sprites have been taken care of, for now. Still, I'm gradually plugging away at it, so we'll see how that goes.
The overall coloring scheme is thus - regular colors for the regular soldiers, blue for navigators, white/gray for medics, green for engineers, red for leaders and gold for commanders. That said, some of them deviate from that color scheme, depending on their original colors.
Current list of recolors consists of Chtonites, Floaters, Mutons, Reptoids, Sectoids and Snakemen. Anthropods don't have any notable ranks, so they're out of the running unless that changes.
If anyone wants to test it out, let me know your experiences.
