Every pixel is a whole Credit.

Credits are the paint and Argonauts are the canvas.

Each Credonaut starts with an Argonaut. I drop the background and swap every pixel for a whole Credit, around two hundred real Credits per piece, and never recolor them.

I sorted the Credits into color families, dark to light.

For each Argonaut the code builds a new palette every time: each of its colors gets a family, light shades take light Credits and dark shades take dark ones.

So no two Credonauts are the same, even from one Argonaut.
