CONCLUSION
This commentary has intended to shed light on the need for research and discussion that emphasizes the prevalence of preference based on skin color in America’s workforce— particularly within the boards of corporate America. Most past research neglects to look at discrimination outside of the normal dichotomous comparisons of Blacks and Whites as groups consisting of homogenous individuals. Given the increasing number of biracial and multiracial Americans, more research in this area should be performed so that Americans can become more aware of the prevalence of color bias in our society. Studies of this nature will perhaps not only enhance their awareness, but also challenge their acceptance of the common belief that whiteness signifies graciousness and beauty (Hill, 2000).
Additionally, research and discussions of this nature will help to substantiate, and in some ways expand, current theories regarding privilege and similarity attraction. It is no secret we live in a society where being White affords many privileges that are not equally awarded to those who are not White (McIntosh, 1993). Possibly, however, the privilege one receives extends beyond their race, and is deeply rooted in their skin color—where darker skin equates to fewer privileges. Similarly, ideologies surrounding colorism seem to further confirm Byrne’s Similarity Attraction Theory, which states people tend to be more attracted to and have a greater comfort level around individuals who are similar to themselves (1971). It is therefore not surprising that lighter-skinned Blacks would be advantaged in the workplace where Whites are most likely making the hiring decisions.
Further, discussion and research of this nature could also help combat some of the irony that has long existed in social science research of race and race relations. While most social scientist who perform research of this nature make claim that the purpose of their research is to address, and hopefully falsify, negative perceptions and stereotypes surrounding various races, their grouping of individuals into homogenous groups, and assuming life experiences must all be the same for all Blacks or all Whites, does nothing more than perpetuate those very stereotypes they are attempting to falsify. When people are forced to look at races and ethnicities through a heterogeneous lens, it causes them to look at a racial or ethnic group in a way where longstanding stereotypes no longer seem accurate or appropriate.
Moreover, as mentioned earlier, given the increasing number of companies and organizations that are employing affirmative action policies in their selection processes, determining the possible presence of skin tone preference is paramount. Companies must be more cognizant of the colorism issue in many of their human resource related procedures. While statistics may continue to show that the number of minorities in corporate America is continuing to rise, they are not reporting the possibility that there is a disproportionate number of lighter complexioned minorities getting these jobs (particularly those at the senior executive level).
The only way we are going to begin to combat some of the inequities that result due to common beliefs and ideologies associated with colorism, is by becoming more aware of the prejudices we have regarding skin tone. Society and the media paints us a picture of lighter skin equating to intelligence, likeability, competency, attractiveness, etc., and a much more dismal and bleak picture is given for those who have darker skin. These images are extremely powerful, in that they alter our immediate perceptions of individuals who must then “fit” into the pictures we have been exposed to. For instance, if one was to imagine a

Black physician, attorney, politician, or CEO, more than likely, most of these images would be of a light-skinned Black. Whereas, if images of a Black factory worker, garbage collector, janitor, or prisoner were conjured up, more than likely they would be of darker pigmentation than those previously listed.
We must begin to combat these negative associations of dark skin and lower expectations, incited fear, and basic incivility. There was a brief period of time during the Black Power Movement where the Black community began to contest these notions that have damaging effects to the self-esteem of Blacks. This period, however, was short-lived, and chants of “Black is beautiful” are not too often still heard. Mantras of this nature must be recited once more if society and the media’s representation of Blackness and dark skin are going to change. The more we challenge these images, and our own belief systems, the greater the likelihood Black children of future generations will only be encouraged to come out of the sun because of the potentially harmful effects of UV radiation, and not because of the probable negative ramifications of having dark skin.
