So I made virtually two identical billboards, one for Aardvark and one for African Buffalo. They both use the exact same color for the background, and yet one appears a lot lighter in-game. Both are using unlit screens. I have confirmed in GIMP that they are the exact same color, were both exported as JPG files, both were exported with identical settings... I honestly don't get why the color is different. Either it's a bug, or hopefully someone will be able to tell me what I did wrong!
