Learning to recognize exclusion

Writing — read the piece

Meant to show
Nobody, on purpose. The empty chair is the person the team did not think to invite, and noticing it is the skill the paper teaches.
Asked for
A team huddled at a whiteboard covered in sticky notes, one empty chair pulled slightly away from the table

Why these three

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

  1. SeedSHA-256 of learning-to-recognize-exclusion, 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 = 276°.
  3. GeometryThe third byte modulo 4 picks complementary, which adds 0°, 180°, 40°.
  4. WobbleThree more bytes shift each by up to ±12° — −8.0°, +6.2°, +8.4° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#8750c5268° at 60% saturation, 77% value#8dcf72102° at 45% saturation, 81% value#893a69325° at 58% saturation, 54% 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.
