I could experiment with those in the future.

I rather like to keep things as much on the simple side as possible though, too many additional adornments and colors on the screen in general can sometimes cause different problems like distraction, or sometimes confusion about what the special meaning of the various colors are.

There's also a kind of general problem with axis colors that I've run into in the past, which is when the local grid axes of each viewport are colored with red for horizontal, and green for vertical, it tends to lead to confusion about why the front view for example has a green line when it is actually pointing up in the world z axis direction. That's another reason why I have tended to stay away from axis colors.

I may be able to kind of relax this avoidance in the future because it seems that I've been successful with moving way from the "local cplane in each viewport" model that I set up in Rhino to a more "global cplane" type system in MoI.
