Sorry, but this question is the epitome of cringe. I'm sure it is not intended as such, but it is the exact opposite of the color-blind ideal. You get to color-blindness by ... err ... practicing color-blindness?
I don't hold color blindness as an ideal. I know that human beings are hard wired to quickly determine in-group/out-group and skin color is a salient trait for that distinction. Not the only one of course, but we're never going to be blind to skin color.
What we can aspire to, you might call "color irrelevance". That in any particular endeavor, the relevance of one's skin color goes to zero. I don't believe we'll get there by ignoring the ways in which we individually and collectively, intentionally or not, let skin color shape our behavior and systems.
