Midnight Blue to Denim gradient
Midnight Blue (#191970) into Denim (#1560bd) — 16° 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, #191970 0%, #1560bd 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, #191970 0%, #1560bd 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, #191970 0%, #191a71 8.28%, #191d74 16.03%, #1a2279 23.35%, #1a287f 30.32%, #1b2e86 37.03%, #1b358e 43.56%, #1b3d96 50%, #1a449e 56.44%, #194ba6 62.97%, #1852ad 69.68%, #1758b4 76.65%, #165cb9 83.97%, #155fbc 91.72%, #1560bd 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.

Report
- white ink: worst 6.11:1 at 100% (AA); black ink: worst 1.41:1 at 0% (fails AA) → use white text.
- Banding medium: ~19px bands at 1440px — add grain 38 (≈3% 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.
