Copper to Sage Green gradient
Copper (#b87333) into Sage Green (#9caf88) — 69° 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 oklab — both colours are in the palette and the hue gap is small enough that the straight line stays clean.
OKLab and OKLCH, side by side
OKLab
Open in maker →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.
linear-gradient(135deg in oklab, #b87333 0%, #9caf88 100%)
OKLCH (shorter hue)
Open in maker →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.
linear-gradient(135deg in oklch shorter hue, #b87333 0%, #9caf88 100%)
And the sRGB line most tools draw, for comparison — the number is the chroma that survives at the dullest point.
Eased and mesh
Eased (soft)
Open in maker →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.
linear-gradient(135deg in oklab, #b87333 0%, #b87435 8.28%, #b77739 16.03%, #b67b3f 23.35%, #b48046 30.32%, #b2854f 37.03%, #b08c58 43.56%, #ad9260 50%, #aa9869 56.44%, #a79e71 62.97%, #a4a479 69.68%, #a1a87f 76.65%, #9eac84 83.97%, #9dae87 91.72%, #9caf88 100%)
Mesh
Open in maker →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 2.36:1 at 100% (fails AA); black ink: worst 5.54:1 at 0% (AA) → use black text.
- Banding high: ~17px bands at 1440px — add grain 35 (≈2% soft-light noise) or shorten the ramp.

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.
