I made a custom game colors to my liking. Some notable changes.
Pink swapped to orange so that Sera's orange doesnt have pink as their color.
Made Cyan into grey as Sera's grey is in that slot. (Cyan is now the final color slot).
Replaced white with civilian tan (new civ color is dark blue).
Replaced original orange slot with dark brown.
I'm also releasing this so others can tweak their colors, just note that you can't modify sera colors because of shaders and what not, so they'll always stay the same in their slot. (blue will always be blue, etc).
