Yikes, what happened to the color scheme of the terrain map mode?
Flatland - plateau is totally indistinguishable for me (probably a color blind thing once again?).
Is Plateau green now?
At risk of sounding like a broken record: green-yellow-orange is near-impossible color scheme for the majority of colorblind people.
About 1/12 men has colorblindness. Considering the PDX game demographic, 1/12 players will have issues with these colors.
Regardless of color, flatlands-plateau really needs a better contrast (imo there was nothing wrong with the previous scheme, was the previous color scheme really that poorly received?)
EDIT -
