Yeah these ranks aren't perfect but it is best I can do, I think. I know they're not as good as originals, but at least they're different (and I'm really satisfied with the 'bubbles' rank pic for Swabbies, speaks so much about how fleeting their life is...
); they wouldn't look good in another color, besides, the limiting factor is Base-scape palette, which has only half of the colors:
- grayscale
- gold
- red
- camo green
- alien alloy
- reddish grey (Power Suit color)
- brass
- some brown->purple thingy that isn't available in Battlescape
- and, blue
(attached: very not gold/blue armor for reference
)
