Colour to colour
Sage Green to Dark Olive Green gradient
Sage Green (#9caf88) into Dark Olive Green (#556b2f) — 3° 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, #9caf88 0%, #556b2f 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, #9caf88 0%, #556b2f 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, #9caf88 0%, #9bae87 8.28%, #98ab83 16.03%, #93a77d 23.35%, #8da176 30.32%, #879b6e 37.03%, #7f9465 43.56%, #788c5c 50%, #708552 56.44%, #697e49 62.97%, #627841 69.68%, #5d733a 76.65%, #596f34 83.97%, #566c30 91.72%, #556b2f 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: #788c5c; background-image: radial-gradient(circle farthest-corner at 15.83% 12.67%, rgba(85, 107, 47, 0.876) 0%, rgba(85, 107, 47, 0) 45.4%), radial-gradient(circle farthest-corner at 48.64% 55.52%, rgba(156, 175, 136, 0.802) 0%, rgba(156, 175, 136, 0) 50.56%); background-image: radial-gradient(circle farthest-corner at 15.83% 12.67%, oklch(from #556b2f l c h / 0.8763) 0%, rgb(from #556b2f r g b / 0) 45.4%), radial-gradient(circle farthest-corner at 48.64% 55.52%, oklch(from #9caf88 l c h / 0.8016) 0%, rgb(from #9caf88 r g b / 0) 50.56%);
Report
- white ink: worst 2.36:1 at 0% (fails AA); black ink: worst 3.53:1 at 100% (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: ~16px bands at 1440px — add grain 33 (≈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.
