Drawing for Who writes the alt text for a picture nobody drew?.

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.

Writing — read the piece

Asked for
A woman studying a framed picture and writing a description on a card while a man listens through headphones beside her

Why these three

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

  1. SeedSHA-256 of who-writes-the-alt-text-for-a-picture-nobody-drew, 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 = 54°.
  3. GeometryThe third byte modulo 4 picks complementary, which adds 0°, 180°, 40°.
  4. WobbleThree more bytes shift each by up to ±12° — +1.6°, +0.0°, +9.4° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#a8a25a55° at 47% saturation, 66% value#263298234° at 75% saturation, 60% value#64ac48103° at 58% saturation, 67% value

Saturation never drops below 72% and value never below 78%, which is what keeps a hue reading as the color it was chosen to be rather than as a dark. More on how these are made.
