Colour to colour
Ivory to Amber gradient
Ivory (#fffff0) into Amber (#ffbf00) — 23° 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, #fffff0 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, #fffff0 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, #fffff0 0%, #fffeee 8.28%, #fffce7 16.03%, #fff8dc 23.35%, #fff3cf 30.32%, #ffedbf 37.03%, #ffe7ad 43.56%, #ffe09a 50%, #ffd985 56.44%, #ffd370 62.97%, #ffcd5b 69.68%, #ffc744 76.65%, #ffc32d 83.97%, #ffc014 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: #ffe09a; background-image: radial-gradient(circle farthest-corner at 53.9% 78.52%, rgba(255, 191, 0, 0.805) 0%, rgba(255, 191, 0, 0) 45.88%), radial-gradient(circle farthest-corner at 42.31% 32.57%, rgba(255, 255, 240, 0.718) 0%, rgba(255, 255, 240, 0) 59%); background-image: radial-gradient(circle farthest-corner at 53.9% 78.52%, oklch(from #ffbf00 l c h / 0.8053) 0%, rgb(from #ffbf00 r g b / 0) 45.88%), radial-gradient(circle farthest-corner at 42.31% 32.57%, oklch(from #fffff0 l c h / 0.7181) 0%, rgb(from #fffff0 r g b / 0) 59%);
Report
- white ink: worst 1.01:1 at 0% (fails AA); black ink: worst 12.70:1 at 100% (AA) → use black text.
- White text disappears completely at 0% (1.00:1 crossing).
- Banding medium: ~6px bands at 1440px — add grain 10 (≈1% 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.
