Colour blindness is not a way of combatting racism.

If you have a real world system, and you bias it heavily to be unequal, then you try and correct it by biasing it to be equal, the average output is still vastly unequal, and the absolute best case scenario you can hope for is that it will trend towards equality over time without ever reaching it.

There's a reason that people who actually study and think about the topic come out as antiracist and people who don't think it about it except when it inconveniences them just wish everyone would stop talking about it and we could pretend like it didn't exist.
