Colour to colour
Forest Green to Royal Blue gradient
Forest Green (#228b22) into Royal Blue (#4169e1) — 124° 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, #228b22 0%, #4169e1 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, #228b22 0%, #4169e1 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, #228b22 0%, #228b28 8.28%, #218a36 16.03%, #208a47 23.35%, #208858 30.32%, #21876b 37.03%, #23847e 43.56%, #278190 50%, #2b7ea2 56.44%, #307ab2 62.97%, #3575c1 69.68%, #3a71ce 76.65%, #3e6dd8 83.97%, #406adf 91.72%, #4169e1 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: #278190; background-image: radial-gradient(circle farthest-corner at 91.18% 34.54%, rgba(65, 105, 225, 0.762) 0%, rgba(65, 105, 225, 0) 47.2%), radial-gradient(circle farthest-corner at 47.34% 7.16%, rgba(34, 139, 34, 0.869) 0%, rgba(34, 139, 34, 0) 56.34%); background-image: radial-gradient(circle farthest-corner at 91.18% 34.54%, oklch(from #4169e1 l c h / 0.7618) 0%, rgb(from #4169e1 r g b / 0) 47.2%), radial-gradient(circle farthest-corner at 47.34% 7.16%, oklch(from #228b22 l c h / 0.8692) 0%, rgb(from #228b22 r g b / 0) 56.34%);
Report
- white ink: worst 4.37:1 at 5% (AA-large only); black ink: worst 4.32:1 at 100% (AA-large only) → 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 15 (≈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.
