My armour is white because it needed to be to make the icon I wanted back in Halo 2. I've kept the same layout since then. I couldn't care less about the colour itself. --- Ash nazg durbatulūk, ash nazg gimbatul, ash nazg thrakatulūk agh burzum-ishi krimpatul.
Ice/Cobalt(Or Blue) works fine for me. Either that or white/teal are aesthetically pleasing with the armor I have, and that's enough for me. Black/red is only mildly annoying when it's someone named "XxXZooperEpikSkillzSniper1337MegaProXxX" (I really don't think anyone would pick that name, though... Just an example ._.) or some random mess of characters like that, and even then I don't really mind. People have their tastes and if they like their videogame Supersoldier avatar to be, in your words, "Dark and cool", they are entirely free to do so. --- Rarity is best Pony. Yes, I'm a Brony. No, I'm not gonna try to get you to watch the show or dislike you if you don't. People can like different things.
