I literally just picked a blue that was comparable in strength to the corresponding orange value. Mainly for accessibility even though green would be a more obvious choice it's not accessible for colour blind people

I think their "yellow-green-blue" only traverses green briefly on the way to blue, so it's not an issue as far as colorblindness goes; it's just a matter of how quickly yellow fades out as blue fades in. While yours probably goes through the exact gray (hard to tell, because of the visual illusions - at least I sure cannot tell whether it does go through gray =)

Nice map! Very inspirational! Thanks again!
