Changing color of Ethiopia or Zanzibar trade nodes

[Philadelphus]

I noticed recently that the Ethiopia and Zanzibar trade nodes have pretty much the same color, and not only that, they actually touch in one province:

Can you tell which province belongs to which node? (Hint: The coastal provinces are all part of the Zanzibar node, the inland ones are Ethiopian.) I don't think it should be too difficult to change the color of one or the other of them so that it's not exactly the same.

The culture groups in Indochina have this exact same problem. It would be very helpful if a dev could fix this sometime in the near future.

There are loads, like the Hudson bay / St lawrence, 2 in india (cannot remember their names), there is a lot of other UI things that have very similar colours but cannot remember them off the top of my head. Will edit this next time I'm in game on Europa so i can check.
