Simple request - greater skin color range

[Tgr]

Hi-

Simple request here. Is there a way to extend the color palette for colonists to be slightly more inclusive of people with darker skin tones? Currently the range appears to stop only at the bottom left image.



Get out of here in advance with any racist bullshit or ranting about SJWs, please. There's hundreds of millions of people alive today with darker skin tones than that currently appear in game, which is also weird because in the Rimworld setting you could easily have entire planets with nonwhite populations. It would also add just a tiny bit more visual variation to colonists.

If anyone knows how to adjust this that would be interesting to figure out.
