cool idea - i tried to pick perceptually separate colours and thought blue and red would work, but turns it's confusing for some people. I might add "colorblind" mode and use your colour range.

"colorblind mode" is an antipattern. Using more contrasting colors and using other distinguishing features such as shape and texture benefits all users.
