Colour to colour
Charcoal to Blush Pink gradient
Charcoal (#36454f) into Blush Pink (#e8b4b8) — 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, #36454f 0%, #e8b4b8 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, #36454f 0%, #e8b4b8 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, #36454f 0%, #384750 8.28%, #3f4b54 16.03%, #4a515b 23.35%, #575a63 30.32%, #67646c 37.03%, #796f77 43.56%, #8b7b82 50%, #9f878d 56.44%, #b19298 62.97%, #c29da2 69.68%, #d2a6ab 76.65%, #ddaeb2 83.97%, #e5b2b6 91.72%, #e8b4b8 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: #8b7b82; background-image: radial-gradient(circle farthest-corner at 7.03% 76.78%, rgba(232, 180, 184, 0.779) 0%, rgba(232, 180, 184, 0) 56.16%), radial-gradient(circle farthest-corner at 18.25% 26.39%, rgba(54, 69, 79, 0.878) 0%, rgba(54, 69, 79, 0) 58.6%); background-image: radial-gradient(circle farthest-corner at 7.03% 76.78%, oklch(from #e8b4b8 l c h / 0.7785) 0%, rgb(from #e8b4b8 r g b / 0) 56.16%), radial-gradient(circle farthest-corner at 18.25% 26.39%, oklch(from #36454f l c h / 0.8783) 0%, rgb(from #36454f r g b / 0) 58.6%);
Report
- white ink: worst 1.80:1 at 100% (fails AA); black ink: worst 2.12:1 at 0% (fails AA) → use black text.
- Neither ink passes AA at the worst point — treat as decorative or add a scrim (rgba(0,0,0,.35) typically lifts white ink past 4:1).
- Banding medium: ~8px bands at 1440px — add grain 16 (≈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.
