Color Blind Mode?
I play Catan Universe all the time and I am color blind. Some of the playing pieces are difficult to tell apart for me. Would Catan ever consider installing a color blind mode? Certain colors are much easier to tell apart than others for color blind people, or even including stripes or +/- signs on top of the pieces would make it easier to tell apart. I choose red as my default playing piece color because it's easiest for me to see. But, whenever you run into someone else who has selected red you can be auto-assigned a different color which can be difficult for me to see.
This suggestion has been requested for several years by the fact of this post and no Dev has even decided to respond.
