A Sunday on the Diatom Lake

This painter has only nine pure pigments, and she never mixes them on the palette. Every dot follows one rule: compare the colour the scene needs at that spot with what the dots already there add up to, then choose the pure pigment that brings the mix closest. Mixing happens in your eye, which is optical mixing, as in Seurat. The scene shows a lake under the 720° sun, a diatom bloom, and Patricia on a moss raft. Slide step back to blur the dots together, and tap to paint a patch faster. Every 20,000 dots are a reservation on the ledger.

LIT: pointillism (Seurat and Signac, 1880s) relied on optical mixing, and the dots here are opaque, so the mixing is roughly additive averaging. Diatom blooms tint lake water olive to brown. MODEL: greedy error-minimising pigment choice in RGB. ANALOGY: an eye that steps back = Gaussian blur.

The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS').
