Drawing for Whose accessibility is it when you did not build it?.

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.

Whose accessibility is it when you did not build it?

Writing — read the piece

Meant to show
A nurse signing onboarding documents in a corridor with gloves on. The screen is the vendor's, the new hire is the company's, and the problem is hers either way.
Asked for
A young woman in scrubs and a navy hijab in a corridor, gloved thumb hovering over a phone, a badge swinging on its lanyard
Drawn with (triad)

Why these three

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

  1. SeedSHA-256 of whose-accessibility-is-it-when-you-did-not-build-it, 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 = 19°.
  3. GeometryThe third byte modulo 4 picks triad, which adds 0°, 120°, 240°.
  4. WobbleThree more bytes shift each by up to ±12° — +11.7°, +6.0°, +4.7° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#855f3731° at 59% saturation, 52% value#3ccf7a145° at 71% saturation, 81% value#8352ce264° at 60% saturation, 81% 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.
