- **Source:** [Golden Hour on CSS Crème](https://csscreme.com/themes/golden-hour)
- **Default mode:** dark
- **Tags:** dark, warm, gradient
- **Install as a real shadcn/ui theme:** `npx shadcn@latest add https://csscreme.com/r/golden-hour.json`
- **Fingerprint:** `fnv1a-feec9a05` — a hash of the token set below. It changes only when a token changes.
- **Verify this copy:** call the MCP tool `verify_design_md` with `{ "id": "golden-hour", "fingerprint": "fnv1a-feec9a05" }`

## Semantic color roles

Six roles carry the identity. Everything else in this file is derived from them.

| Role | Hex | OKLCH | Use it for |
| --- | --- | --- | --- |
| `bg` | `#16120E` | `oklch(18.6% 0.010 67.1)` | page background |
| `surface` | `#241D16` | `oklch(23.7% 0.017 66.9)` | cards, panels, popovers |
| `primary` | `#F2A93B` | `oklch(78.7% 0.147 73.0)` | brand actions: primary buttons, links, focus rings |
| `accent` | `#FF6B6B` | `oklch(71.2% 0.181 22.8)` | secondary emphasis only, never a second primary |
| `text` | `#F7EEDF` | `oklch(95.2% 0.022 80.7)` | body and heading text |
| `muted` | `#A2917C` | `oklch(66.6% 0.036 73.0)` | secondary text, borders, disabled states |

## Full token set (shadcn/ui, both modes)

Colors are OKLCH (Tailwind v4 / shadcn native). Brand colors are identical in both modes by design:
only the neutrals move, and they keep their hue, so light and dark read as the same design system.

**What is measured and what is derived.** The six roles are the source. `chart-*` and `sidebar-*` follow
fixed rules over them (chart-1 = primary, chart-2 = accent, chart-3/4 = primary rotated ±40°, chart-5 = the
midpoint of primary and accent; sidebar maps onto surface, border and primary). `shadow-*` is the foreground
colour at a fixed opacity per step. None of those is a measurement, and an agent should treat them as
defaults it may override, unlike the six roles, which it may not.

## Typography

- **Headings:** Playfair Display
- **Body:** Inter

## Shape and rhythm

- **Radius:** `12px` (the `--radius` token; derive smaller/larger from it, do not invent new values)
- **Spacing scale:** 4px base · 4 / 8 / 12 / 16 / 24 / 40

## Contrast, measured

Computed from the tokens above in dark mode, not asserted. Ratios are WCAG 2.1 relative luminance.

| Pair | Foreground | Background | Ratio | Verdict |
| --- | --- | --- | --- | --- |
| Body text on page background | `#F7EEDF` | `#16120E` | 16.19:1 | AAA |
| Body text on card | `#F7EEDF` | `#241D16` | 14.46:1 | AAA |
| Muted text on page background | `#A2917C` | `#16120E` | 6.1:1 | AA |
| Button label on primary | `#0b0b0f` | `#F2A93B` | 9.84:1 | AAA |
| Button label on accent | `#0b0b0f` | `#FF6B6B` | 7.08:1 | AAA |

## Rules for the agent

These are constraints, not suggestions. Each one is checkable against the tables above.

1. **Use only the tokens listed here.** Do not introduce a hex value that is not in the token table. If
   you need an in-between shade, mix two existing tokens rather than inventing a new hue.
2. **`#F2A93B` (primary) is the only call-to-action color.** One primary action per view. `accent`
   is for secondary emphasis and must never be styled as a second primary button.
3. **Never restyle brand colors between light and dark.** Only neutrals change mode. A theme whose
   primary shifts between modes is a different theme.
4. **Respect the radius token.** Every corner derives from `12px`. Mixed radii across a view is
   the most common tell of generated UI.
5. **Stay on the spacing scale.** 4px base · 4 / 8 / 12 / 16 / 24 / 40. No arbitrary pixel values.
6. **Do not drop below the contrast ratios above.** If a combination you need is not in the contrast
   table, compute it before shipping it. Text under 4.5:1 fails AA.
7. **Headings in Playfair Display, body in Inter.** Do not add a third family.
8. **Use the semantic role, not the raw color.** Write `var(--primary)`, never `#F2A93B`, so the
   theme stays swappable.
