A kneeling person in gloves spreads mortar with a trowel while laying a low brick wall.

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.

When is a standard still cheap to change?

Why these three

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

  1. SeedSHA-256 of when-is-a-standard-still-cheap-to-change, 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 = 69°.
  3. GeometryThe third byte modulo 4 picks triad, which adds 0°, 120°, 240°.
  4. WobbleThree more bytes shift each by up to ±12° — +1.0°, +4.1°, +5.2° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#b5ce3c70° at 71% saturation, 81% value#408aa0194° at 60% saturation, 63% value#c255a7315° at 56% saturation, 76% 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.
