Please answer a question about the following article about Race (human categorization):

Eduardo Bonilla-Silva, Sociology professor at Duke University, remarks, "I contend that racism is, more than anything else, a matter of group power; it is about a dominant racial group (whites) striving to maintain its systemic advantages and minorities fighting to subvert the racial status quo."  The types of practices that take place under this new color-blind racism is subtle, institutionalized, and supposedly not racial. Color-blind racism thrives on the idea that race is no longer an issue in the United States. There are contradictions between the alleged color-blindness of most whites and the persistence of a color-coded system of inequality.

What idea does color-blind racism thrive on?
that race is no longer an issue
