Eddit, if you havent noticed, I posted short info how to edit those palettes earlier in the same thread, as well as in the other, months ago

Rhye experimented with mixing colours a lot, it's interesting, though the effect often depends on unit, some look great, others don't, and I have
a bit of units to think of. I changed civ colours because I needed frog-green for slann, and something closer to red for Nippon, but might change more now, as I see it becoming trendy

You downloaded PTW version (and you asked for PTW version first, so you got the answer). To play with Conquests, you also need to download the patches. See first post in this thread, and read it whole, carefully. You fill find all files needed for Conquest there.
