Four people sit around a table with papers, facing a wall covered in sticky notes.

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.

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.

A drawing

This is a museum label beside a picture. The drawing comes first, and everything about it comes after.

From top to bottom

  1. At the top, the site header: my name, which goes home, then links to Writing, Work, Signal, Tools and Resume, then Settings, where you choose the drawings, light or dark, and movement.
  2. A link back to all the illustrations.
  3. The drawing, large.
  4. Links to the previous and next drawing, and where this one falls among them. The left and right arrow keys go there too.
  5. The title of the piece the drawing belongs to, with a link to read it. On this page the heading comes after the drawing.
  6. What the drawing was meant to show, what was asked for, and its three colors.
  7. Why these three: how the colors were picked, with a color wheel and the steps.
  8. At the bottom, the footer: a note on how this site is built, links to Illustrations, Pens, Concepts and Accessibility, this Describe this page button, then GitHub, LinkedIn and email.
