# Build brief — an original marketing website in the taste of Lumen
> Reference: https://www.lumen.me · UIDiscovery: https://uidiscovery.com/sites/lumen · captured 2026-09-22 at a 1440px desktop viewport (+ 390px iPhone shots) · [full page](https://uidiscovery.com/media/captures/lumen/full.png) · [scroll video](https://uidiscovery.com/media/captures/lumen/preview.mp4)
## 1. Goal
Build an original marketing website for **[the user's brand]** that feels as considered as Lumen — same structure, rhythm and polish, entirely new identity and content.
## 2. Originality rules
- Build an ORIGINAL design for the user's own brand in the same *taste* as Lumen: structure, rhythm, hierarchy, palette mood and type pairing.
- Never reuse Lumen's logo, name, product imagery, illustrations, icons, screenshots or copy. Write new copy for the user's product.
- If the user hasn't said what their product is, ask first (or use clearly marked placeholders like [Brand], [Product], [Audience]).
- Reference screenshots are for looking at, not for embedding or tracing.
## 3. The taste, in short
- Lumen (lumen.me): Health & Fitness marketing website, dark.
- 14 sections: Hero → Logo cloud → Features → Content → Features → Call to action → Features → Content → Statement.
- Spacing: about a screen per idea (median section ≈675px).
- Hero headline: 3 words — short and punchy; keep yours under ~9.
- Type: one family (Inter). Imagery: mostly photography, some typography with little or no imagery.
## 4. Page structure (top to bottom)
### 1. Hero — state what the product is and for whom in one glance, and offer the primary action.
- Layout: headline-led stack: eyebrow → H1 → supporting line → actions, with a visual beside or below. About one full screen (887px at 1440), page background; no images (type-led); primary + secondary button.
- Slots: Eyebrow / announcement pill (optional); H1 (~3 words, like the reference); Supporting line, 1–2 sentences; Primary + secondary action; No image — let type and colour carry it.
- Topic (tone/length only — never reuse): “Hack Your Metabolism”

## 5. Design system
### Colour
| Role | Hex | Use | Contrast on background |
|---|---|---|---|
| background | `#000000` | page background | — |
| foreground | `#ffffff` | body text, headings | 21.0:1 |
| accent | `#7c57fd` | primary buttons, links, highlights — sparingly | 4.6:1 |
| surface | `#211537` | cards, inputs, alternate bands | text on it 17.1:1 |
| muted | `#666666` | secondary text, borders | 3.7:1 — borders / large text only |
Captured palette: `#000000` `#ffffff` `#e6e6e6` `#7c57fd` `#211537` `#666666`. Roles are assigned automatically — sanity-check them against the screenshot. Keep the palette's *mood* (dark, cool) and proportions; swap the accent for the user's brand colour.
### Tokens
```css
:root {
--background: #000000;
--foreground: #ffffff;
--accent: #7c57fd;
--surface: #211537;
--muted: #666666;
--font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
--font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
--radius: 12px; /* calibrate from the screenshot */
}
/* Tailwind v4 — in globals.css after @import "tailwindcss"; */
@theme {
--color-background: var(--background);
--color-foreground: var(--foreground);
--color-accent: var(--accent);
--color-surface: var(--surface);
--color-muted: var(--muted);
--font-heading: var(--font-heading);
--font-sans: var(--font-body);
}
```
### Typography
- Headings: **Inter** (Google Fonts) — reference uses Inter. Free to use — load it directly.
- Body: same family — a single-family system; create contrast with size and weight, not a second face.
- Scale (starting point, sizes weren't measured — calibrate against the 1440px screenshot): display clamp(2.75rem, 6vw, 5rem), h2 clamp(1.75rem, 3vw, 2.5rem), h3 1.25rem, body 1rem–1.125rem / 1.6, small 0.875rem. Headings: tight tracking (-0.02em), line-height 1.05–1.15.
### Spacing & rhythm
Sections run ≈675px tall at 1440 (median; range 189–1052px, captures cap at 1700px) — roughly a screen per idea. Start with 96–120px vertical padding per section on desktop and about two-thirds of that on mobile. One continuous background — separate sections with space and type, not colour bands. 8px spacing grid, 1200–1280px max content width, 24px (mobile) / 32–48px (desktop) gutters.
### Shape, depth & theme
On dark, separate layers with 1px borders at ~8–12% white and soft glows instead of drop shadows. Read exact corner radius, border and shadow treatment from the screenshots. Dark-first; for a light mode swap background ↔ foreground, lighten the surface, keep the accent and re-check contrast.
## 6. Imagery plan
Measured from 8 section screenshots: mostly **photography**, some typography with little or no imagery (dark, cool, Health & Fitness). Still glance at the linked screenshots to match the exact mood.
### Slot 1 · 3. Features → photography
- Photography, seen in the capture (people). (measured from the screenshot) Count: a set of ~2 in one consistent style. Aspect: 4:3. Look first: [ref 1](https://uidiscovery.com/media/captures/lumen/s-03.webp)
- **Stock** — “healthy breakfast bowl dark”: [Unsplash](https://unsplash.com/s/photos/healthy-breakfast-bowl-dark?orientation=landscape) · [Pexels](https://www.pexels.com/search/healthy%20breakfast%20bowl%20dark/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/healthy%20breakfast%20bowl%20dark/?orientation=horizontal)
- **Generate** — `Photograph: healthy breakfast bowl. Composition: tight crop, identical framing and background across the whole set. Lighting: low-key, moody directional light with deep shadows. Cool colour grade that sits on #000000, #7c57fd, #211537. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 4:3. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 2 · 5. Features → product UI
- Product UI — screenshots or mockups of the app, seen in the capture. (measured from the screenshot) Count: 1. Aspect: 4:3. Look first: [ref 1](https://uidiscovery.com/media/captures/lumen/s-05.webp)

- **Generate** — `Product-shot backdrop for a UI screenshot: smooth dark gradient from #000000 to #211537 with a soft #7c57fd glow behind the centre, subtle floor shadow, empty centre area where a screenshot will be placed. Lighting: low-key, moody directional light with deep shadows. Aspect ratio 4:3. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people. No UI elements.`
- Build the UI itself in HTML/CSS with realistic sample data from YOUR product (or screenshot your real app). Don't generate UI as an image and don't reuse the reference's screenshots. Stock/AI is only for the backdrop or device frame.

Aspect ratio 4:3. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 7 · 11. Call to action → photography
- Health & Fitness references lean on photography. Count: a collage of several photos with one consistent colour grade. Aspect: 21:9 (background). Look first: [ref 1](https://uidiscovery.com/media/captures/lumen/s-11.webp)
- **Stock** — “runner at sunrise wide shot dark”: [Unsplash](https://unsplash.com/s/photos/runner-at-sunrise-wide-shot-dark?orientation=landscape) · [Pexels](https://www.pexels.com/search/runner%20at%20sunrise%20wide%20shot%20dark/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/runner%20at%20sunrise%20wide%20shot%20dark/?orientation=horizontal)

No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
### Slot 8 · 12. Features → photography (uncertain)
- Health & Fitness references lean on photography; 73 elements suggests icons/thumbnails mixed in. Count: a collage of several photos with one consistent colour grade. Aspect: 4:3. Look first: [ref 1](https://uidiscovery.com/media/captures/lumen/s-12.webp)
- **Stock** — “healthy breakfast bowl wide shot dark”: [Unsplash](https://unsplash.com/s/photos/healthy-breakfast-bowl-wide-shot-dark?orientation=landscape) · [Pexels](https://www.pexels.com/search/healthy%20breakfast%20bowl%20wide%20shot%20dark/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/healthy%20breakfast%20bowl%20wide%20shot%20dark/?orientation=horizontal)
- **Generate** — `Photograph: healthy breakfast bowl wide shot. Composition: tight crop, identical framing and background across the whole set. Lighting: low-key, moody directional light with deep shadows. Cool colour grade that sits on #000000, #7c57fd, #211537. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 4:3. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- **No imagery (type-led)** — 1. Hero, 4. Content, 10. Features: No imagery needed — type, spacing and colour do the work. If the screenshot shows a background graphic, rebuild it in CSS (gradient, grid, noise) or a short muted video, not a stock photo.
- **Logos** — 2. Logo cloud: Never generate or stock-source logos. Use your real customers'/partners' marks with permission (monochrome, equal height), or neutral wordmark placeholders until you have them. Integration icons: each tool's official brand kit (Simple Icons is a quick start; trademarks still apply).
### If the screenshots show a different style
Open the refs first and name what you actually see (photo / product UI / illustration / abstract gradient or 3D / type only). If it differs from the guess, switch routes — UI is built in code, type-only needs no image, otherwise:
- **abstract 3D / gradient** — generate `Abstract 3D render: soft, glossy glass-like shapes and a smooth gradient in #7c57fd and #666666 on a #000000 background. Lighting: low-key, moody directional light with deep shadows; cool tone. Minimal and calm, generous negative space on one side for text. Aspect ratio 16:9. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“abstract dark gradient 3d” on Unsplash](https://unsplash.com/s/photos/abstract-dark-gradient-3d?orientation=landscape) (same query works on Pexels/Pixabay)
- **illustration** — generate `Flat vector illustration: calm person meditating, friendly simplified shapes, limited palette of #000000, #7c57fd, #211537 plus one soft neutral, plenty of empty background, consistent line weight, cool mood. Aspect ratio 16:9. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.` · stock: [“wellness flat illustration” on Unsplash](https://unsplash.com/s/photos/wellness-flat-illustration?orientation=landscape) (same query works on Pexels/Pixabay)
- **Licences:** Unsplash and Pexels images are free for commercial use under their own licences; Pixabay under the Pixabay Content License. Check each image's page before use, credit the photographer when asked (good practice anyway), and skip images showing logos, trademarks, branded products or identifiable people without a release.
- **AI generation:** the prompts work with any image model (GPT Image, Imagen, Flux, Midjourney, Firefly, SDXL…) — check its commercial-use terms. Never put the reference brand's name or “in the style of <brand>” in a prompt.
- **Never** download, trace or re-host the reference's own images, illustrations, product shots or logos.
## 7. Build steps
1. Confirm brand, product, audience and the primary action with the user.
2. Set up the tokens (CSS variables / Tailwind @theme) and load the fonts.
3. Build the sections in order, mobile-first, with each reference screenshot open.
4. Write original copy for every slot — match length and tone, never the words.
5. Source every image via the imagery plan (stock or generated); compress it and record credits.
6. Run the checklist at 390 / 768 / 1440px and fix what fails.
## 8. Acceptance checklist
- [ ] Responsive at 390px, 768px and 1440px — no horizontal scroll, tap targets ≥ 44px on mobile.
- [ ] Colour contrast WCAG AA: 4.5:1 body text, 3:1 large text and UI; visible focus states; full keyboard navigation.
- [ ] Semantic HTML: one <h1>, ordered headings, landmarks (header/nav/main/footer), labelled form fields, alt text on meaningful images.
- [ ] Performance: modern image formats with width/height set, lazy-load below the fold, ≤ 2 font families with font-display: swap, LCP < 2.5s.
- [ ] prefers-reduced-motion respected; animations under ~300ms and never blocking content.
- [ ] Originality: no copied logos, images, illustrations or copy from the reference; every image licensed or generated; credits recorded.
## 9. If you use Next.js + Tailwind
Paste the @theme block into globals.css, load fonts with next/font/google, make each section a server component in components/sections/, use next/image with explicit sizes, and keep client components for interactive bits only (menus, toggles, accordions).
