Adds Vercel's Geist design system color ramps.
Hue ramps
8 hue ramps, each with 10 steps (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000):
gray,blue,red,amber,green,teal,purple,pink. Plus a 2-stepbackground(single colors, surfaced asother).Light-mode sRGB values, normalized from Geist's published
hsla()light tokens.Hand-tuning evidence
Geist is clearly hand-tuned, not generated by a locked-L algorithm. Computed OKLCH L per step across the 7 chromatic ramps (excluding gray):
The mid-to-dark steps (600-800) show L stddev well above the 0.02 algorithmic threshold. Amber notably runs much lighter at the peak-chroma steps (L = 0.82 at step 700 vs ~0.58 for blue/purple/pink) — a hand-tuned choice to preserve perceived warmth and chroma in yellows, rather than forcing equal lightness across hues.

Source
The Geist palette is documented at https://vercel.com/geist/colors. The raw values were taken from the published
geist-colorspackage source: https://github.com/ephraimduncan/geist-colors/blob/main/src/light.ts (saved verbatim todata/raw/geist.ts, including a handful of typos in the upstream file that do not affect the normalized hex values).Generated by Claude Code
