Noticing that someone is a member of a racial (or any other group) is benign. It is just a fact, nothing more. What you do with that information is what matters. As an individual, I can claim that I am colour/gender/whatever-blind but _in the world that exists_, that is just ignoring what certain groups of people are experiencing from other people who are not as agnostic to these characteristics as you claim to be.

Also, I doubt that there is any place on earth that is colourblind and somehow race is not a problem. And no, "nobody speaks about it =/= the problem does not exist. Most countries have some issues with race, are largely homogeneous (sometimes despite spending decades brutally exploiting countries with other races a century or two ago), or have a long-running kerfuffle with some local minority.
