Colour to colour
Emerald Green to Mustard Yellow gradient
Emerald Green (#50c878) into Mustard Yellow (#ffdb58) — 58° 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, #50c878 0%, #ffdb58 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, #50c878 0%, #ffdb58 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, #50c878 0%, #54c878 8.28%, #5fc977 16.03%, #6ecb76 23.35%, #7ecd74 30.32%, #90cf71 37.03%, #a2d16f 43.56%, #b4d36c 50%, #c5d568 56.44%, #d4d765 62.97%, #e2d861 69.68%, #eed95e 76.65%, #f7da5b 83.97%, #fddb59 91.72%, #ffdb58 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: #b4d36c; background-image: radial-gradient(circle farthest-corner at 22.18% 58.1%, rgba(80, 200, 120, 0.845) 0%, rgba(80, 200, 120, 0) 47.52%), radial-gradient(circle farthest-corner at 90.86% 47.4%, rgba(255, 219, 88, 0.743) 0%, rgba(255, 219, 88, 0) 59.03%); background-image: radial-gradient(circle farthest-corner at 22.18% 58.1%, oklch(from #50c878 l c h / 0.8451) 0%, rgb(from #50c878 r g b / 0) 47.52%), radial-gradient(circle farthest-corner at 90.86% 47.4%, oklch(from #ffdb58 l c h / 0.7433) 0%, rgb(from #ffdb58 r g b / 0) 59.03%);
Report
- white ink: worst 1.35:1 at 100% (fails AA); black ink: worst 9.87:1 at 0% (AA) → use black text.
- Banding high: ~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.
