Two bearded men in glasses look at a laptop on a desk with papers and a mug.

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 ccds, 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 = 64°.
  3. GeometryThe third byte modulo 4 picks split, which adds 0°, 150°, 210°.
  4. WobbleThree more bytes shift each by up to ±12° — 11.9°, 6.3°, 5.1° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#b9aa3c53° at 68% saturation, 73% value#3f7db4208° at 65% saturation, 71% value#763cb2269° at 66% saturation, 70% 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.
