 ### Coloring algorithm
 Start with 2 of the 3 red, green and blue values fixed at either 0 or 255, then increase the other R, G or B value in a given number of increments based on the number of colors needed, repeat this for seven cases and you get a maximum of 1792 colors (7*256). Note that white repeats 3 times, at the end of cases 2, 4 and 6.
