ColorCompass was an experiment with combining three simple gradients 
where each color channel increases in increments of 1 from 0 at the 
center to 255 at the extremes.

The red channel runs vertically, the blue runs horizontally, and the 
green runs diagonally.

This is accomplished by simply looping through a discrete version of the 
xy plane and setting each point's red and blue values to the absolute 
value of the x and y coordinates, while green is set to the absolute 
value of the sum of x and y.

I have been informed that this combination results in orange at the 
north and south compass points, teal at the east and west, and white and 
magenta in the corners.

In addition to the full image, I have included monochrome images of the 
three separate gradients.
