I mention that white is aesthetic in the above posts, but you are likely right about the pure white that you see displayed. To get the armour all white I have to basically do the equivalent of shouting at the AI that the colour is white (often for each individual piece of clothing). Otherwise it starts bleeding in colours from elsewhere (for Alice red from her hair colour and black seems to commonly bleed in for everyone). I have to specify eye colour on the follow-up where the face on the first image is rebuilt to match the character. If you include eye colour on the main (Alice's being blue) then you will start to find blue clothing items coming up.
So it's likely a combination of me shouting in AI "ITS FUCKING WHITE!" and the AI being very literal in making it pure white.
Usually you can use variants to make it less pure, cream, off-white.. google helps in working out what common colour variants the AI is likely to understand. Despite all that shouting, black, silver, blue, red still occasionally gets in there, like with the screens below. It's a shame because I really wanted to have two-tone colour schemes for a lot of the characters, but the colour bleed and inaccuracy of colour application just make the number of variations so much bigger that you find maybe 1 in 30 generations where they were consistent for a simple outfit (ludicrously higher numbers if the outfit is elaborate), whereas with using a single clear colour that error rate drops to more like 1 in 5.
