It has been 128 years since the last country abolished slavery, and 53 years since Martin Luther King, Jr.'s "I have a dream" speech, yet we still live in a world where the color of our skin gives a first and leaves a lasting impression. Angelica Dass's portrait project, Humanae, challenges how we think about skin color and ethnicity. What does it mean for us to be "black, white, yellow, red." Is it the eye, the nose, the mouth, the hair? Or does it have to do with our origin, nationality, or bank account? Watch this personal TED talk about Humanae and Dass's pursuit to document humanity's "true" colors.
