A woman in profile with hair in a bun faces a computer monitor, surrounded by swirling clouds and stars.

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.

How do we learn a spec nobody reads?

Why these three

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

  1. SeedSHA-256 of how-do-we-learn-a-spec-nobody-reads, 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° — 0.8°, 6.7°, 0.5° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#d45dd3301° at 56% saturation, 83% value#81a05485° at 48% saturation, 63% value#5dd89c151° at 57% saturation, 85% 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.
