Exactly this! Okay, maybe a bit sarcastic, but that how I feel about this also.
You DON’T get anymore usable info using more colors than the 3 most obvious. Perhaps those who fancy it, should use at least a 10-band EQ capable mixer as well.
I personally never liked the overly red coloring on Serato, Traktor, Pioneer and the others who mimic each other. Even changed it to blue, where posible.
However, I get the idea to change the 3 colors to something else or to set them to 1 color, like opted above.
