Colour to colour
Olive Green to Medium Slate Blue gradient
Olive Green (#808000) into Medium Slate Blue (#7b68ee) — 176° 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 176° > 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, #808000 0%, #7b68ee 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, #808000 0%, #7b68ee 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, #808000 0%, #7d8105 8.28%, #728515 16.03%, #5f8b2a 23.35%, #3d9142 30.32%, #00965f 37.03%, #00957f 43.56%, #009397 50%, #0090af 56.44%, #008bca 62.97%, #0082e6 69.68%, #4878ee 76.65%, #666ff0 83.97%, #766aef 91.72%, #7b68ee 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: #797c93; background-image: radial-gradient(circle farthest-corner at 29.68% 89.42%, rgba(123, 104, 238, 0.881) 0%, rgba(123, 104, 238, 0) 53.71%), radial-gradient(circle farthest-corner at 21.95% 23.87%, rgba(128, 128, 0, 0.83) 0%, rgba(128, 128, 0, 0) 50.54%); background-image: radial-gradient(circle farthest-corner at 29.68% 89.42%, oklch(from #7b68ee l c h / 0.881) 0%, rgb(from #7b68ee r g b / 0) 53.71%), radial-gradient(circle farthest-corner at 21.95% 23.87%, oklch(from #808000 l c h / 0.8298) 0%, rgb(from #808000 r g b / 0) 50.54%);
Report
- white ink: worst 3.72:1 at 42% (AA-large only); black ink: worst 5.00:1 at 2% (AA) → use black text.
- Banding medium: ~6px bands at 1440px — add grain 11 (≈1% soft-light noise) or shorten the ramp.
- 25/64 samples left sRGB by more than 5% and were gamut-mapped (oklch shorter); expect slight hue drift there.
