Colour to colour
Copper to Steel Blue gradient
Copper (#b87333) into Steel Blue (#4682b4) — 175° 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 175° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.
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%, #4682b4 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%, #4682b4 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 oklch shorter hue, #b87333 0%, #b97236 8.28%, #bc6f3f 16.03%, #be6a4d 23.35%, #be6760 30.32%, #bb6574 37.03%, #b36589 43.56%, #a7689d 50%, #986cac 56.44%, #8671b6 62.97%, #7377ba 69.68%, #627bba 76.65%, #537fb8 83.97%, #4a81b5 91.72%, #4682b4 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.
background-color: #877f7d; background-image: radial-gradient(circle farthest-corner at 21.78% 40.19%, rgba(184, 115, 51, 0.803) 0%, rgba(184, 115, 51, 0) 45.48%), radial-gradient(circle farthest-corner at 66.9% 35.82%, rgba(70, 130, 180, 0.881) 0%, rgba(70, 130, 180, 0) 58.84%); background-image: radial-gradient(circle farthest-corner at 21.78% 40.19%, oklch(from #b87333 l c h / 0.8028) 0%, rgb(from #b87333 r g b / 0) 45.48%), radial-gradient(circle farthest-corner at 66.9% 35.82%, oklch(from #4682b4 l c h / 0.8808) 0%, rgb(from #4682b4 r g b / 0) 58.84%);
Report
- white ink: worst 3.79:1 at 0% (AA-large only); black ink: worst 5.03:1 at 75% (AA) → use black text.
- Banding high: ~11px bands at 1440px — add grain 23 (≈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.
