1. Starting with #000000, create a grayscale gradient to #FFFFFF.
2. Create a gradient from #010000 to #FFFEFE with the correct length to encompass all red values between. Go through each of the 5 other hues possible for the same gradient length.
3. Continue the process, creating a new gradient starting with an increased starting red value and ending with a decreasing green and blue value. Create the rest of the other gradients of the same length at increasing hue values.
4. Repeat step 3 until the starting red value has reached 255, the ending green and blue values have reached 0, and the final hue has been reached.
