What is interesting about this topic is that it is still a "big deal" to many people, which is why it is still a topic to be discussed. However, discussing it keeps the topic a "big deal" to many people as opposed to the assumption that discussing something combats ignorance and changes people's thoughts and actions.
I have found that instead of thinking and talking about this "color complex" I just make it a point to correct (usually, black) people when I see or hear them displaying colorisms or hair texturisms. For instance, if I hear some ignorant soul say "good hair" or say "I need to stay out of the sun because I'm black enough as is," I go on (what my friend calls) my Angela Davis speech. I say "no such thing as 'good hair' unless you're talking about healthy hair" and "no such thing as being 'black enough' but you need to stay out of the sun to protect yourself from UV rays and skin cancer, not getting darker. Interestingly enough, your beautiful dark skin protects you from the sun's rays and skin cancer more than lighter or white skin does." I remember when a classmate told me when I was little that I needed to stay out of the sun to make sure that I stayed pretty and lightskinned--my family doesn't talk crazy like that so I was really shocked when I was told that by an outsider. No, I don't need to stay out of the sun to avoid getting shades darker but I do need to stay out of the sun because I have less melanin to protect my skin.
Either case, people have generally learned not to make certain comments around me. I could be changing the world if I force everyone to interact with me on a daily basis. Then I'll be their #1 source of socialization.
