I have definitely seen this before but it seems pretty more on the extremities. Although that's where all these ideas started, good and bad. Not just with magic but the idea of white/black, light/dark as a placeholder for good/bad qualities being racist. Seems much more obviously related to illumination than color to me (scary/bad things happen in the dark/blackness/night).
