Not sure how that article is supposed to support your point. It talks about policies that were basically targeted at white people, just not explicitly so. If you say: "Every home owner gets free cash!", then of course that policy will favor white people, and rich people, because those are the people who own the houses.
That does not in any way discredit the idea that if you have a colorblind policy that for example mandates that schools in poor areas get extra funding will help equalize the playing field, even if it's not targeted at black people, but at poor people as a whole. It's all about actually targeting those policies so that the people who need the help the most, get the help.
Actually, that is precisely what it does. The entire point is that in the US (and elsewhere too) policies that are colorblind are policies that are "basically targeted at white people, just not explicitly so."
