I have blue/green color blindness. The gray scale from un-used paths and the red scale from over crowding or amenity need are hard to differentiate for me. I am always asking my husband to help me tell the difference, and even he, who is not colorblind, sometimes cannot tell for certain. Is it possible to have a color blind mode in the options menu, to change the red scale for amenity needs and over crowding into a blue/green/yellow/orange scale (any of these would work for me), to make it easier to tell it apart from the gray scale? Thanks
