Notes

Long-form writing on color, palettes, and the tooling around them.

• Anatomy of a colormap (2026-05-30): A scroll-driven teardown of every component that makes a colormap useful — anchor stops, oklab mixing, the load-bearing lightness axis, diverging midpoints, and the grayscale test.
• How sharp should the pivot be? (2026-05-30): Diverging colormaps pivot around a center — but how abruptly? A scroll-driven look at pivot sharpness, a county map you can sharpen by hand, why an asymmetric domain still wants a symmetric scale, and a comparison of how smoothly common diverging maps turn at the pivot.
