This program calculates primes, takes their remainder^{ [1]} and then places a color accordingly. The shapes are quiet interesting.^{ [2]}

## Footnotes

- ▲ The formula for the color 𝑐 at prime 𝑝 with modulo 𝑚 is 𝑐 = 𝑝 mod 𝑚. (𝑚 = 𝟣𝟢 on the left, 𝟤𝟧𝟧 on the right and 𝟧𝟢𝟢 on the bottom)
- ▲ [2020-07-16] Looking back at it, I am quite surprised that I stumbled upon “analyzing” prime remainders back then, not knowing how deeply rooted in number theory they are.
