Today i have been reminded of a thread that lived on the previous incarnation of the forums (archive here), where people showcased their color schemes different from the official ones for the factions. Quite a bit of time has passed since then and we have new armies and even a new faction (O12), so go ahead and brag of your awesome alternative color scheme!
I am partial to Yujing with white or cream plates, here is mine but there is so much good examples of this online.
That tinbot Brigada was an inspiration and I might STILL do one to add to my own collection of... 6 Brigadas now? 7? Man they are a nice design.
I´ve been told that those WIP12 PanO mugs cannot really distinguish friend or foe if you are in blue...
A bit specific but there's this thread in the faction part of the forum https://forum.corvusbelli.com/threads/invincible-alternate-colour-schemes.33671/ It's more a thread about getting inspiration and opinion but there's some nice alt schemes there.
The only Force where i am really close to the studio scheme are my JSA. the colourpalette is the same but there is a lot more red. As the Domaro, Aragoto and karakuri were my first miniatures there is a visable difference to more recent miniatures. My Combined/shas are Green, purple and yellow My Ikari/Druze/Mercs are pretty close to the original Druze coloursheme but with additional Tan: My Yu Jing are Blue with orange Trims, Teal capes and White masks for the upright citizen, criminals have orange masks and dead People black masks: Additionaly Troops with mimetism, camo or those skills have lilac swords, lenses and lights opposed to red on nonmimetic Troopers. And at the time i am working on some testmodels for my Spiral Tohaa inspired by different species of Sealife so i guess no studio scheme as well.
To index the info here, there was an alternative colours scheme thread for the O12 in the faction section: https://forum.corvusbelli.com/threads/0-12-alternate-color-schemes.34247/
