What do the colors mean on Better Settlers?
The colors surely match the colors of the resource cards and the actual hexes:


maroon - brick
dark green - wood
light green - sheep
yellow - wheat
gray - ore


And the blank orange hex would be the desert.




(clockwise from bottom left, that's sheep, wheat, ore, brick, and wood;  the center is desert, and there's an extra wood cut off on the bottom)
