Steel Blue to Maroon gradient
Steel Blue (#4682b4) into Maroon (#800000) — 143° 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 143° > 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, #4682b4 0%, #800000 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, #4682b4 0%, #800000 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, #4682b4 0%, #4780b4 8.28%, #4c7cb4 16.03%, #5374b4 23.35%, #5d6ab0 30.32%, #685ea9 37.03%, #72519d 43.56%, #7b448c 50%, #813677 56.44%, #852960 62.97%, #861d48 69.68%, #851132 76.65%, #83071d 83.97%, #810109 91.72%, #800000 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: #745362; background-image: radial-gradient(circle farthest-corner at 79.73% 23.38%, rgba(128, 0, 0, 0.729) 0%, rgba(128, 0, 0, 0) 50.95%), radial-gradient(circle farthest-corner at 11.49% 69.75%, rgba(70, 130, 180, 0.845) 0%, rgba(70, 130, 180, 0) 58.09%); background-image: radial-gradient(circle farthest-corner at 79.73% 23.38%, oklch(from #800000 l c h / 0.7287) 0%, rgb(from #800000 r g b / 0) 50.95%), radial-gradient(circle farthest-corner at 11.49% 69.75%, oklch(from #4682b4 l c h / 0.8448) 0%, rgb(from #4682b4 r g b / 0) 58.09%);
Report
- white ink: worst 4.11:1 at 0% (AA-large only); black ink: worst 1.92:1 at 100% (fails AA) → use white 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: ~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.
