I wanted to play with the visual concept of pure black/pure white on opposing sides and colour where they intersect, to communicate that we should shed our biases and see every human being as a citizen of the planet in order to bring about the most positive and colourful future. The heads were deliberately designed to be indistinguishable as any particular race, gender, nationality, religion, etc. (The colouring of them with RGB 0,0,0 and 255,255,255 is meant to communicate a conceptual idea of extremes, with no reference to skin colours.)
