FWIW, if one clicks on the color to choose a new color, one can put in specific hex#s for colors.
Perhaps this is why I have not run into this concern - not a bug, obviously coded to be - even when using the same colors for every option (jersey, #, helmet blahblah).
I've gone full monochrome.
If you are keen, perhaps test to see if using hex #s is a workaround?
Again, nice catch!
The less the AI does the better hehehhe!
