Sea Green to Burgundy gradient
Sea Green (#2e8b57) into Burgundy (#800020) — 136° 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, #2e8b57 0%, #800020 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, #2e8b57 0%, #800020 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, #2e8b57 0%, #328a56 8.28%, #3d8554 16.03%, #497f50 23.35%, #55774c 30.32%, #5f6d46 37.03%, #686241 43.56%, #6f573b 50%, #754b35 56.44%, #793e2f 62.97%, #7c312a 69.68%, #7e2326 76.65%, #7f1523 83.97%, #800621 91.72%, #800020 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: #6f573b; background-image: radial-gradient(circle farthest-corner at 36.79% 78.17%, rgba(128, 0, 32, 0.797) 0%, rgba(128, 0, 32, 0) 48.37%), radial-gradient(circle farthest-corner at 51.02% 21.72%, rgba(46, 139, 87, 0.78) 0%, rgba(46, 139, 87, 0) 58.45%); background-image: radial-gradient(circle farthest-corner at 36.79% 78.17%, oklch(from #800020 l c h / 0.7973) 0%, rgb(from #800020 r g b / 0) 48.37%), radial-gradient(circle farthest-corner at 51.02% 21.72%, oklch(from #2e8b57 l c h / 0.7798) 0%, rgb(from #2e8b57 r g b / 0) 58.45%);
Report
- white ink: worst 4.25:1 at 0% (AA-large only); black ink: worst 1.94:1 at 100% (fails AA) → use white 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 high: ~10px bands at 1440px — add grain 21 (≈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.
