I'm using Photoshop CS6 and IrfanView, I would like to get some instructions on how to recolor and save the Stellaris city sets, which I assume should (if done right) be a simple method
here is one example of what I would like to get from a mammalian city color swap (mammalian_01_city_I04.dds)
I hope someone has the time to explain the procedure so I can do further similar edits myself, as I believe many of the vanilla city sets would look far better (or good as additional options) after a simple Irfanview-style color swap
