This was shot at an angle, so you could see that I paint the sides, too. The square is square. I did this because I wanted to unite everyone, which I did in the extension. There are 7 colors, 3 cool and passive, (blue, indigo, violet, going to black), and 3 warm and active, (red, orange, yellow, going to white). With the 7th, green, being the uniter, as green is the symbol of regeneration.
