Turn the prime number sequence into a stripe of named PIGMENTUM colors.
Primes are the atoms of arithmetic — the numbers divisible only by one and themselves — and their distribution has fascinated mathematicians for millennia. They never fall into a simple repeating pattern, yet they are not quite random either. Turning them into color is a way to look at that distribution with fresh eyes.
Each prime is mapped deterministically to a hue (the prime modulo 360 degrees) at full saturation and medium lightness, then resolved to the exact named PIGMENTUM color closest to that hue. Because the rule is fixed, the same prime always yields the same color, so the stripe is a stable, reproducible portrait of the sequence 2, 3, 5, 7, 11, 13 and onward.
As you increase the count, watch how the colors cycle. The modular mapping wraps the hue wheel every 360, so primes that differ by multiples of 360 land on similar colors — a visible echo of the arithmetic. It is decorative rather than a research instrument, but it makes the relentless, irregular march of the primes tangible.
