Note: While this sense can be used with positive connotations of freedom from racial prejudice, it often suggests a failure or refusal to acknowledge or address the many racial inequities that exist in society, or to acknowledge important aspects of racial identity.

Many sociologists, though, are extremely critical of colorblindness as an ideology. They argue that as the mechanisms that reproduce racial inequality have become more covert and obscure than they were during the era of open, legal segregation, the language of explicit racism has given way to a discourse of colorblindness.Adia Harvey Wingfield
They [critics] argue that since race is a major contributing factor in all sorts of societal outcomes, from who goes to jail to what educational opportunities a child has, to adopt color-blindness as an ideology is to ignore important discrepancies, thereby allowing them to fester.Jesse Singal
