Colour to colour
Crimson to Amber gradient
Crimson (#dc143c) into Amber (#ffbf00) — 64° 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, #dc143c 0%, #ffbf00 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, #dc143c 0%, #ffbf00 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, #dc143c 0%, #dd1b3c 8.28%, #df293c 16.03%, #e2393b 23.35%, #e5493a 30.32%, #e95939 37.03%, #ed6a37 43.56%, #f17a33 50%, #f5892f 56.44%, #f89729 62.97%, #fba422 69.68%, #fdaf1a 76.65%, #feb80f 83.97%, #ffbd04 91.72%, #ffbf00 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: #f17a33; background-image: radial-gradient(circle farthest-corner at 93.63% 70.6%, rgba(220, 20, 60, 0.892) 0%, rgba(220, 20, 60, 0) 56.1%), radial-gradient(circle farthest-corner at 56.74% 83.41%, rgba(255, 191, 0, 0.827) 0%, rgba(255, 191, 0, 0) 55.06%); background-image: radial-gradient(circle farthest-corner at 93.63% 70.6%, oklch(from #dc143c l c h / 0.8921) 0%, rgb(from #dc143c r g b / 0) 56.1%), radial-gradient(circle farthest-corner at 56.74% 83.41%, oklch(from #ffbf00 l c h / 0.8273) 0%, rgb(from #ffbf00 r g b / 0) 55.06%);
Report
- white ink: worst 1.65:1 at 100% (fails AA); black ink: worst 4.21:1 at 0% (AA-large only) → use black text.
- Body text fails AA everywhere on this gradient; large text (≥24px / 19px bold) is fine. Add a scrim or lower the chroma for body copy.
- Banding medium: ~8px bands at 1440px — add grain 17 (≈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.
