From photographer Angelica Dass’s (Rio de Janeiro, 1979) project, Humanae. The following is from the “About tab of the project Tumblr:
Humanae is a chromatic inventory, a project that reflects on the colors beyond the borders of our codes by referencing the PANTONE® color scheme.
…based on a series of portraits whose background is dyed with the exact Pantone® tone extracted from a sample of 11x11 pixels of the portrayed’s face. The project’s objective is to record and catalog all possible human skin tones.
