You should probably add these to one of the terrain sets, it's a shame to hide these in the comments!

I know that colors do not all have the same value ("lightness") to them, but I'll try fiddling with the HSV sliders for select color ranges and attempt to turn the green versions into autumn ones. Same might to a degree for winter with desaturation/greyscale.

Edit: Godot has a value to "modulate" the tiles with a color, which on first look seems okay to create tiles for seasons or daytimes.
