penn.heat: Create a color gradient

Description

Creates a gradient of colors ranging from light Penn blue (Penn blue with increased Value in HSV) to Penn blue, to Penn red, to light Penn yellow. It is best to provide an odd number, so that there is always an equal number of colors on either side of the midpoint, which will be Penn blue. For example, if you want a gradient from -1 to 1 or equivalent, an n = 11, will give 5 colors on either side of 0, each representing a 20

Usage
