Christians, Sikhs, Jews, Wiccans, Shiites, and Aztecs all have significant days or beliefs connected in some way to the number thirteen. For example, there was a baker’s dozen at the last supper. Italians, Colgate University, and Taylor Swift alike considered 13 to be lucky. The United States began with thirteen colonies and the thirteenth amendment to the US Constitution abolished slavery.

I call this technique a false-color image, restrained to a particular subset of colors. The method is inspired by oil painting, where the artist chooses a palette and also pays homage to the classic technique of hand-colored photography. Although the colors are conceivable, they deviate from reality. The process shares other aspects with painting, being applied selectively to areas on the image. Painters will often tint shadows and highlights differently in order to give a greater illusion of depth as well as evoking an emotional response. Additionally a warm-toned subject appears to protrude from cool-toned surroundings.
