Brand gradient
Hershey's gradient
The gradient Hershey's's published colour tokens imply, derived by a pure function of the palette: primary → secondary in OKLab (OKLCH shorter hue when the hues are more than 140° apart; a tonal ramp when they are within ΔE 0.15), then a hero background with an ink that passes AA at the worst point along the line, a button surface with hover and active states, and the variant contact sheet. Same inputs, same gradients, forever — which is what makes them citable; the same values are served as --brand-gradient in the brand's brand.css.

Hero and button
Hero background
Open in maker →Chroma ×0.35 so it can carry text; ink white (inkFor at the midpoint). Passes AA for that ink at the worst point (10.44:1) without adjusting L.
linear-gradient(135deg in oklab, #2b1718 0%, #2e405e 100%)
bg-linear-to-br/oklab from-[#2b1718] to-[#2e405e]
Button / CTA
Open in maker →ΔL 0.08 top→bottom in the primary's hue (a lit surface, not a rainbow); hover L +0.03, active L −0.03. White ink passes AA on the surface and both states (worst 14.07:1).
linear-gradient(180deg in oklch shorter hue, #4b0b14 0%, #330004 100%)
bg-linear-to-b/oklch from-[#4b0b14] to-[#330004]
Variants
Tonal ramp
Open in maker →linear-gradient(135deg in oklch shorter hue, #763337 0%, #3f000b 50%, #040000 100%)
bg-linear-to-br/oklch from-[#763337] via-[#3f000b] to-[#040000]
Analogous
Open in maker →Partner hue from the analogous rule at the source colour's lightness.
linear-gradient(135deg in oklab, #3f000b 0%, #3b0025 100%)
bg-linear-to-br/oklab from-[#3f000b] to-[#3b0025]
Complementary
Open in maker →Partner hue from the complementary rule at the source colour's lightness. ΔH 179° > 140° — interpolating in oklch (shorter hue) keeps the midpoint saturated.
linear-gradient(135deg in oklch shorter hue, #3f000b 0%, #002324 100%)
bg-linear-to-br/oklch from-[#3f000b] to-[#002324]
Triadic
Open in maker →Partner hue from the triadic rule at the source colour's lightness.
linear-gradient(135deg in oklab, #3f000b 0%, #082500 100%)
bg-linear-to-br/oklab from-[#3f000b] to-[#082500]
Report — brand gradient
- white ink: worst 10.84:1 at 100% (AA); black ink: worst 1.22:1 at 0% (fails AA) → use white text.
- Banding high: ~11px bands at 1440px — add grain 22 (≈2% soft-light noise) or shorten the ramp.

The custom properties below are byte-identical to the gradient block in brand.css; the DTCG token is what tokens.json carries.

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.
