Pixel Art Puzzle: Hueloop

Hueloop is a pixel art puzzle about order.

A picture made of coloured pixels sits inside a belt. Below it, painters wait in columns, each with a colour and a number of shots. Send one round and at every stop it looks straight into the picture: if the first pixel it sees is its own colour, it knocks it out. Anything else hides what is behind it.

A painter that comes back with shots left waits on a spare slot, ready to go again. Fill every slot and the belt jams. So the outer colours have to go first, and every painter sent too early costs you a slot. Par comes from our own solver, run before the pack ever ships, so every picture is known to be solvable and it all works in airplane mode.
