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. Prime Diamonds builds on ideas from ColorCompass. Working on the sum rule from the green part of ColorCompass, I took the absolute values of x and y prior to summing them, which if I'm correct, should result, not in a diagonal gradient, but a square one that is rotated 45-degrees to the grid. If I simply left all three color channels as a plain square gradient, I would just end up with a grayscale, so to add some variety, I take the sum of the coordinates and divide it by the primes 2, 3, and 5. If the sum is a multiple of 2, that pixel gets red, a multiple of 3, it gets green, and if its a multiple of 5, it gets blue. This should result in a multicolor pattern of concentric squares, of red, green, and blue for numbers with only one of 2, 3, or 5 in their prime facterization, yellow, cyan, and magenta for numbers with two of 2, 3, and 5 in their prime factorization, and gray for numbers that are multiples of 30(The least common multiple of 2, 3, and 5, with black for 1 and all numbers with 7 as their smallest prime factor. The intensity is based on taking the remainder of the x+y sum divided by 255, allowing the image to extend beyond a small patch, and which should result in concentric bands that brighten from their inner edge moving outward. primeSquare is the unmodified version with all three channels having the same base forumla. primeError was an attempt to stretch the red and blue channels into more elongated rhombi, one vertically, the other horizontally, but after generating hte image, I realized the logic should affect brightness, but not shape of the blue and red parts othe pattern. The transformation here is to do the prime division test on the sum, but set intensity based on doubling one of x and y in the sum. primeDiamonds is a second attempt to stretch the red and blue parts of the pattern. This time, x or y is doubled during the summation, and if the sum is divisible by the correct prime, it is modded by 255 to determine the intensity. Note: As of 2024/07/09, none of the primeDiamond variants have been seen by human eyes. I can only comment on the logic that went into generating these images, I cannot confirm for my self that the results are as I expected, and I can only confirm that the code I wrote compiled, ran without obvious error, and the conversion from the .ppm my code generates to .png went without error.
