And I should have added that that function's result is based on a luminance computation of this function:
https://docs.racket-lang.org/gui/Windowing_Functions.html?q=get-label-background#%28def._%28%28lib._mred%2Fmain..rkt%29._get-label-background-color%29%29 and the foreground one. So if there is some way you're controlling those that defeats that computation, that might explain why you're getting the bad colors.
