A long haired person in a coat stands behind a desk with two office chairs and a cup, facing swirling clouds.

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

The opposition backed off by 30 degrees either side, which keeps the contrast without the vibration.

  1. SeedSHA-256 of who-can-afford-to-participate, 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 = 301°.
  3. GeometryThe third byte modulo 4 picks split, which adds 0°, 150°, 210°.
  4. WobbleThree more bytes shift each by up to ±12° — 10.6°, +10.4°, 2.3° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#9a2eae291° at 73% saturation, 68% value#78b25f102° at 47% saturation, 70% value#3d9668149° at 59% saturation, 59% 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.
