Steel Blue to Navy Blue gradient
Steel Blue (#4682b4) into Navy Blue (#000080) — 18° 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, #4682b4 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, #4682b4 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 oklab, #4682b4 0%, #4480b3 8.28%, #407cb1 16.03%, #3a75ae 23.35%, #316dab 30.32%, #2763a6 37.03%, #1d58a1 43.56%, #114c9b 50%, #044096 56.44%, #003490 62.97%, #00288b 69.68%, #001c87 76.65%, #001083 83.97%, #000481 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: #114c9b; background-image: radial-gradient(circle farthest-corner at 13.7% 91.95%, rgba(0, 0, 128, 0.824) 0%, rgba(0, 0, 128, 0) 47.1%), radial-gradient(circle farthest-corner at 53.84% 91.99%, rgba(70, 130, 180, 0.722) 0%, rgba(70, 130, 180, 0) 58.3%); background-image: radial-gradient(circle farthest-corner at 13.7% 91.95%, oklch(from #000080 l c h / 0.8242) 0%, rgb(from #000080 r g b / 0) 47.1%), radial-gradient(circle farthest-corner at 53.84% 91.99%, oklch(from #4682b4 l c h / 0.7222) 0%, rgb(from #4682b4 r g b / 0) 58.3%);
Report
- white ink: worst 4.11:1 at 0% (AA-large only); black ink: worst 1.31:1 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: ~11px bands at 1440px — add grain 23 (≈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.
