Two hands in a buttoned jacket adjust a knob and rail on a workbench machine.

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

Two hues opposite each other, the strongest contrast available, with the third supporting the first.

  1. SeedSHA-256 of what-does-a-model-owe-you-when-it-is-not-sure, 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 = 121°.
  3. GeometryThe third byte modulo 4 picks complementary, which adds 0°, 180°, 40°.
  4. WobbleThree more bytes shift each by up to ±12° — 6.7°, +5.3°, 9.6° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#43bb36114° at 71% saturation, 73% value#8b2e81306° at 67% saturation, 55% value#33bf7c151° at 73% saturation, 75% 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.
