Gradient maker
Same stops, three spaces
Click a bar to interpolate there. The number is how much chroma survives at the dullest point.
Grey/white endpoints carry the other stop's hue (powerless hue), so green→white stays green.
Contrast along the line
WCAG ratio for white and black ink at every point. Shaded = below 4.5:1 for white ink. The marker is the exact worst point.
Easing
Stops are not evenly spaced. x = stop position, y = mix amount. Baked into 12–16 stops, or one colour-hint when that is within 0.02.
Derive from a palette or brand
Paste hexes (primary first) or a public brand slug. Every type is a pure function of the palette — the same contact sheet an agent gets from brand_gradients.
Export
CSS with the interpolation space, Tailwind v4, SVG with correct geometry, a DTCG token, and the PNG.

}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.
