Colorblindness is a popular diversity ideology promoted as a means to intergroup harmony in ethnically diverse nations. While some research suggests that colorblindness reduces intergroup bias, other work suggests that colorblindness may increase it. The present research utilizes a national sample of European New Zealanders to examine whether the relationship between colorblind endorsement and outgroup attitudes is moderated by perceivers' individual differences in social dominance orientation (SDO). Data revealed that for participants low in SDO, colorblind beliefs predicted more negative attitudes toward ethnic minorities. However, for those high in SDO, colorblind beliefs predicted more positive attitudes toward ethnic minorities. Taken together, these findings suggest that colorblindness is not all good or bad for intergroup relations—instead, its effects may depend on perceivers' own egalitarian sentiments.
