|Binomial Probability Density Function|
The probability of each position is then transformed into a color by multiplying it by 960 to get a value for hue, then truncated to a maximum value of 240. 960 is used due to the fact that the highest value for any given cell is roughly 0.25, and I wanted to use the full range of hues.
I created this as I saw the way the numbers on a binomial distribution table moved smoothly from 0+ (very small numbers, but larger than zero) to ~0.25 in a line from upper left to lower right, and wanted to duplicate the appearance with color.
