Sienna to Navy Blue gradient
Sienna (#a0522d) into Navy Blue (#000080) — 141° 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 oklch: ΔH 141° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.
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, #a0522d 0%, #000080 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, #a0522d 0%, #000080 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 oklch shorter hue, #a0522d 0%, #a0502e 8.28%, #9f4a32 16.03%, #9c4138 23.35%, #973742 30.32%, #8f2c4e 37.03%, #83225b 43.56%, #741a68 50%, #621373 56.44%, #4f0d7c 62.97%, #3b0681 69.68%, #290283 76.65%, #180082 83.97%, #070081 91.72%, #000080 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: #4d3f64; background-image: radial-gradient(circle farthest-corner at 56.16% 94.64%, rgba(0, 0, 128, 0.87) 0%, rgba(0, 0, 128, 0) 48.23%), radial-gradient(circle farthest-corner at 70.7% 46.26%, rgba(160, 82, 45, 0.844) 0%, rgba(160, 82, 45, 0) 45.35%); background-image: radial-gradient(circle farthest-corner at 56.16% 94.64%, oklch(from #000080 l c h / 0.8695) 0%, rgb(from #000080 r g b / 0) 48.23%), radial-gradient(circle farthest-corner at 70.7% 46.26%, oklch(from #a0522d l c h / 0.8439) 0%, rgb(from #a0522d r g b / 0) 45.35%);
Report
- white ink: worst 5.62:1 at 0% (AA); black ink: worst 1.31:1 at 100% (fails AA) → use white text.
- Banding medium: ~9px bands at 1440px — add grain 18 (≈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.
