When in doubt, I use google and find hex codes to plonk in. I'm colorblind though, so I can't say I recommend that unless you want to start over-relying on a crutch you don't necessarily need!
Hm, thanks for the tip. I don't have the feeling that I need to do this at the moment. I mostly can point out wrong colours.
*sigh*
I have so little time and since I have evening shifts like every day, I'm feeling a little impatient. This isn't nearly done.
What I wonder about are the colour ramps. In the original screenshot, some colours get less saturated when they get darker. I know that's not irregular, but it makes it hard for me to find ramps that share colours.
Additional, I can't make the armor look geometric as it is supposed to.
