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.

So, you design Data Visualizations. Visualize this: you could go blind tomorrow.
Writing — read the piece
- Meant to show
- A blind analyst hearing the data as sound while her colleague finds the same line on paper: the chart reaching her without a picture.
- Asked for
- A woman in large headphones listening to a chart played as sound, a folded white cane on the desk beside her hand, while a colleague points to the same line on a large printed chart pinned to the wall
- Drawn with (complementary)
#af318c#37af5c#ba515b
Why these three
Two hues opposite each other, the strongest contrast available, with the third supporting the first.
- SeedSHA-256 of
data-visualizations-visualize-this-you-could-go-blind-tomorrow, which is the same every time and different for every piece. - Base hueThe first two bytes as a fraction of 65,535, times 360 = 314°.
- GeometryThe third byte modulo 4 picks complementary, which adds 0°, 180°, 40°.
- WobbleThree more bytes shift each by up to ±12° — +2.9°, +4.9°, +0.6° — so two pieces that draw the same geometry are still not the same shape on the wheel.
- Result
#af318c316° at 72% saturation, 69% value#37af5c139° at 68% saturation, 68% value#ba515b354° at 56% saturation, 73% 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.
