Plz, pour your knowledge over me, I'm rdy.

Q: How do I bake the "_TEAM" texture with the "_DIFF" texture correctly in Gimp/PS?
I just want to have the diffuse texture with the faction colors pre-applied, as I only need it for reference. I've tried to look up tutorials, but being a noob I don't know what to search for, nothing of what I find is relevant.

I'm using Gimp and this is how far I've gotten on my own: I've opened the diffuse texture, added the team texture in a layer above, set the team layer to darken...

That seems to apply the team texture colors to the diffuse texture correctly, but now the ship is cyan, magenta and yellow(primary colors, I know). I've managed to change the magenta to red(it's a vaygr ship) with "colorize", but that makes all other colors from the team texture to apply no color.

It would've made sense to me --as a complete novice-- to use levels or curves, but they seem to focus on RGB instead of CMY and I see no way to change it.

PS. What color is yellow supposed to be? Magenta and cyan is red and white respectively, but what would the third vaygr color be?

(If you don't want to write a small essay, pointing me in the direction of a relevant tutorial is totally fine.)
