Color picking

Min color difference

If a pick is too close to one already chosen, the next color in sort order is used instead. 0 turns this off.

Random offset

Locked colors stay put when you reroll or change settings.

Cleanup

Stray pixels

A stray pixel takes the most common color among its 8 neighbors. Thin means at most one matching neighbor.

Click a swatch to choose a replacement color, or use Pick to take one from the source or shrunk image. Either one locks that color. Buckets = pixels ÷ ammo, rounded up; the last bucket holds the remainder. Per column assumes 5 columns.

Level export

pixels is one row per line of the grid, each value an index into palette. buckets lists the ammo in each bucket, per color. imageSeed comes from the image itself; seedIncrement is how many steps past it the first winnable deal was found, and seed is their sum.
