Hot Pink to Chartreuse gradient

Hot Pink (#ff69b4) into Chartreuse (#7fff00) — 144° apart on the OKLCH hue wheel. Below: the same two stops interpolated in OKLab and in OKLCH, side by side, because the difference is real and most generators never let you see it; then an eased version and a mesh, each with the worst-case contrast for white and black text. The engine's own pick for this pair is oklch: ΔH 144° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.

OKLab and OKLCH, side by side

Aa

A straight line through the a/b plane: the two hues meet halfway and desaturate a little at the midpoint. The safe default — it is what CSS and Tailwind default to.

Chroma and hue interpolate separately, so the midpoint keeps its saturation and the hue travels the short way round the wheel — richer, and it can pass through hues neither colour has.

And the sRGB line most tools draw, for comparison — the number is the chroma that survives at the dullest point.

A cubic-bezier(.4, 0, .6, 1) mix ratio baked into 15 stops: the transition lingers on each colour and moves faster through the middle, which is what makes a gradient read as designed rather than default.

Aa

Both colours as stacked radials over a base, laid out by a seeded Poisson-disc sampler — the same seed gives the same mesh forever. Exports as CSS, SVG and PNG.

Report

  • white ink: worst 1.30:1 at 100% (fails AA); black ink: worst 7.79:1 at 6% (AA) → use black text.
  • Banding medium: ~8px bands at 1440px — add grain 16 (≈2% soft-light noise) or shorten the ramp.
  • 59/64 samples left sRGB by more than 5% and were gamut-mapped (oklch shorter); expect slight hue drift there.

live endpoint

Point any MCP client at the shared gradients endpoint and your agent gets the same engine as this page — make_gradient returns CSS with the interpolation space, Tailwind v4, SVG, a PNG URL, a DTCG token and the contrast report in one call; brand_gradients derives the whole contact sheet from a brand or a palette. Read-only, no key. Every gradient is a /gradients/new/… link: open it, refine, paste it back.
