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.

Work — read the piece

#cb52b1#888540#5bbad8
Why these three
Three points spaced evenly around the wheel — the furthest apart three hues can be.
- SeedSHA-256 of
idea-data-reporting, which is the same every time and different for every piece. - Base hueThe first two bytes as a fraction of 65,535, times 360 = 309°.
- GeometryThe third byte modulo 4 picks triad, which adds 0°, 120°, 240°.
- WobbleThree more bytes shift each by up to ±12° — +3.9°, −10.9°, +5.4° — so two pieces that draw the same geometry are still not the same shape on the wheel.
- Result
#cb52b1313° at 60% saturation, 79% value#88854058° at 52% saturation, 53% value#5bbad8194° at 58% 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.
