A man in a jacket holding a long pole stands in profile beside an open door amid swirling patterns.

Draws this one again — same subject and the same people, a new palette and a new angle on it, described afresh. It replaces the drawing on this page for everyone, until somebody draws another. Costs the site about eight cents, and a few seconds.

Why these three

Three points spaced evenly around the wheel — the furthest apart three hues can be.

  1. SeedSHA-256 of who-was-not-in-the-room-when-the-data-was-designed, which is the same every time and different for every piece.
  2. Base hueThe first two bytes as a fraction of 65,535, times 360 = 28°.
  3. GeometryThe third byte modulo 4 picks triad, which adds 0°, 120°, 240°.
  4. WobbleThree more bytes shift each by up to ±12° — 7.6°, 2.2°, +10.1° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#b0663f21° at 64% saturation, 69% value#50c080146° at 58% saturation, 75% value#71448a278° at 50% saturation, 54% value

Saturation never drops below 72% and value never below 78%, which is what keeps a hue reading as the colour it was chosen to be rather than as a dark. More on how these are made.
