Umbermore
Monochrome minimal online store site on white with a monochrome palette
Light · Monochrome minimal · E-commerce · front-end app (local state)
A light, near-monochrome and restrained visual system for a consumer brand store. Its look rests on 600-weight display type up to 40px, monospace used for labels, metadata or code and a monochrome palette on a white canvas. Apply it to a marketing site or the public pages of an app; the tokens and component specs carry the identity.

What makes it
- 600-weight display type up to 40px
- monospace used for labels, metadata or code
- square corners on controls (0-2px)
- large 16px card corners
- soft layered shadows on raised cards

Spacing and imagery
comfortable density on a 4px base unit; container 1200px; section gap 40px-60px; card padding 12px; element gap 12px-20px; radii tags 2px, cards 16px, images 0px, inputs 2px, buttons 2px; 3 shadow levels
Photography, product screenshots, illustration, line icons. Use placeholder or generated imagery only; partner marks are neutral placeholders in the muted text color. Product views sit in framed panels with the card radius. Photography is shown under a scrim wherever text overlaps it. Icons are outline style at 20-24px in the text or muted color.
Layout
- top navigation: wordmark left, 4-6 text links, primary action right; collapses to a menu sheet under 768px
- centered hero: headline, one-line lede and a primary plus secondary action, visual below
- product grid: image, name, price and quick-add, 4 columns desktop / 2 mobile
- large framed product view on a tinted surface
- feature grid of icon, title and two-line description cells (3-4 columns desktop, 1 column mobile)
- article or story cards with image, kicker, title and date
- closing call-to-action band with heading and primary action
- footer with grouped link columns, legal line and social icons
- content sits in a 1200px centered container with 24px side padding (16px on mobile)
- sections are separated by 40px-60px of vertical space on desktop, roughly half that on mobile

Guardrails
Experience
- Keep one primary action style (#777750 fill, #000000 label) and use it once per view; secondary actions stay outlined or text-only.
- Keep corners square on every control; do not mix in rounded or pill shapes.
- Limit headline sizes to the type scale; the 40px display size appears once per page, in the hero.
- Keep copy short and concrete: one idea per section, with a heading that states the benefit.
Accessibility
- Text, links, focus rings and input borders use only the verified pairs listed in contrast checks.
- Focus ring: 2px solid #000000 with 2px offset on every interactive element.
- Body text is 16px or larger at 1.5 line height; nothing is smaller than 12px.
- Decorative colors (dividers and supporting accents) never carry text or the only signal of state.
- Tabs follow the ARIA tabs pattern with roving tabindex.
- Text over photos or gradients sits on a scrim that keeps it at 4.5:1 against the lightest area.
- Respect prefers-reduced-motion; no parallax or autoplay video without a pause control.
- Some observed colors were moved to the nearest passing shade of the same hue; use the palette values here, not lighter originals.
Security
- Validate every form with a shared zod schema on the client and again in the edge function; reject unknown fields.
- Rate-limit form endpoints per IP and add a honeypot field; store leads in a Supabase table with RLS allowing insert only for anonymous users and select only for staff.
- Set a strict Content-Security-Policy, self-host fonts and icons, and avoid third-party scripts beyond privacy-friendly analytics.
- Open external links with rel="noopener noreferrer" and never put secrets or API keys in client code.
- Checkout goes through a hosted payment provider; the site never handles card data, and prices are re-validated on the server.
Build prompt
The rules every style in the gallery assumes, then this style’s own ten sections, from goal to guardrails. A build in the style also gets its tokens as a file, so the colors and type above are exact.
The rules every style assumes
### How to use these prompts Paste an entry's build prompt into your coding agent as the first message. Each prompt names its own stack, tokens and acceptance criteria; the rules below apply to all of them and can be prepended once per project. ### Engineering baseline - TypeScript strict mode, no `any`, small typed components, feature folders, and one source of truth for design tokens (CSS variables consumed by Tailwind). - Validate every input with a shared zod schema on the client and again on the server or edge function. Never trust client-side checks alone. - Show loading, empty and error states for every async view. Surface errors in plain language with a retry, and log details to the console in development only. - Keep secrets out of the bundle. Only publishable keys (for example a Supabase anon key) belong in client code; service-role keys, API keys and webhooks live in server or edge-function environment variables. ### Data and auth baseline - Enable Row Level Security on every table before inserting data. Default-deny, then add the narrowest policies the feature needs (for a lead form: insert-only for anonymous users, select for a staff role). - Store roles in a separate table checked by a security-definer function, never in a user-editable profile field. - Rate-limit public endpoints (forms, auth, AI calls) and add a honeypot field or captcha to anonymous forms. - Take payments through a hosted checkout and verify webhooks by signature. Never handle raw card data. ### Accessibility and UX baseline - Target WCAG 2.2 AA: 4.5:1 contrast for normal text and 3:1 for large text, input borders, focus rings and meaningful icons or chart lines. Every palette in this catalog lists its verified pairs; re-check with a contrast tool after any color change. - Keep body text at 16px or larger with 1.5 line height, nothing below 12px, no light weights under 24px, and uppercase only for short labels. - Give every interactive element a visible focus ring, full keyboard support, semantic landmarks, labeled form fields, and alt text on meaningful images. - Respect `prefers-reduced-motion` for every animation. Give carousels and drag interactions keyboard and button alternatives, and never auto-advance them. - Build mobile-first and test at 375px, 768px and 1280px. ### Content guardrails - Use original copy, fictional sample data and placeholder or generated imagery. Do not reuse another product's name, logo, screenshots or marketing text. - Partner and customer logo rows use neutral placeholder marks. Label demo testimonials and metrics as samples. Collect the minimum personal data a form needs. ### Style preset baseline - Treat the entry's palette, type scale, radii, spacing and shadows as the complete token set. Do not introduce new colors; derive hover and pressed states by moving one step lighter or darker within the same hue, then re-check contrast. - Colors marked decorative (dividers, supporting accents) never sit behind text and never carry meaning on their own. - Fonts are open Google Fonts chosen to match the observed letterforms. Self-host them with `font-display: swap` and keep to the listed weights. - Keep the signature moves listed for the entry, and keep everything else quiet so they stay recognizable. - One primary action style per view. Secondary actions are outlined or text-only, and links are distinguishable by more than color (underline or weight).
### Goal
Build a responsive light-theme marketing site for a fictional consumer brand store in the "Umbermore" style: near-monochrome and restrained, with 600-weight display type up to 40px, monospace used for labels, metadata or code, square corners on controls (0-2px). Use invented copy and placeholder imagery throughout.
### Stack
React 18 + Vite, TypeScript, Tailwind CSS, shadcn/ui (Radix), lucide-react, TanStack Query, zod, Supabase (form submissions only). Design tokens live as CSS variables and are mapped into the Tailwind theme.
### Pages & layout
Home page sections, in order:
- top navigation: wordmark left, 4-6 text links, primary action right; collapses to a menu sheet under 768px
- centered hero: headline, one-line lede and a primary plus secondary action, visual below
- product grid: image, name, price and quick-add, 4 columns desktop / 2 mobile
- large framed product view on a tinted surface
- feature grid of icon, title and two-line description cells (3-4 columns desktop, 1 column mobile)
- article or story cards with image, kicker, title and date
- closing call-to-action band with heading and primary action
- footer with grouped link columns, legal line and social icons
- content sits in a 1200px centered container with 24px side padding (16px on mobile)
- sections are separated by 40px-60px of vertical space on desktop, roughly half that on mobile
Also build a simple contact page with a lead form and a 404 page in the same style. Test at 375px, 768px and 1280px.

### Data & state
Content comes from typed local collections: Feature{icon, title, body}, Post{slug, title, kicker, excerpt, coverUrl, publishedAt}, Product{slug, name, price, imageUrl, alt, inStock, swatches[]}, Lead{email, name?, message?, createdAt}. The lead form posts to a Supabase edge function. Handle these states:
- images show a surface-colored placeholder until loaded, with alt text if they fail
- forms: inline validation, disabled submit while sending, success message and retryable error
- mobile menu open and closed states
- hover, focus-visible, active and disabled states for every button style
- reduced-motion variant with no transitions beyond opacity
- selected and unselected tab states, with the panel labeled by its tab
- out-of-stock product tile with a disabled add button and 'Notify me' alternative
- cart count badge updates after add
### Accessibility
- Text, links, focus rings and input borders use only the verified pairs listed in contrast checks.
- Focus ring: 2px solid #000000 with 2px offset on every interactive element.

- Images in AVIF/WebP with explicit width and height, lazy-loaded below the fold; preload the hero image and the display font only.
- One h1 per page, descriptive titles and meta descriptions, Open Graph tags with a generated preview image, and a sitemap.
- Target Lighthouse 95+ for performance, accessibility, best practices and SEO.
### Guardrails
- Keep one primary action style (#777750 fill, #000000 label) and use it once per view; secondary actions stay outlined or text-only.
- Keep corners square on every control; do not mix in rounded or pill shapes.
- Limit headline sizes to the type scale; the 40px display size appears once per page, in the hero.
- Keep copy short and concrete: one idea per section, with a heading that states the benefit.
Acceptance criteria:
- Every color in the build comes from the tokens above and every text pair matches a verified contrast pair.
- The page works with keyboard only, shows a visible focus ring everywhere and passes an automated axe check with no violations.
- No real brand names, logos, product screenshots or copied marketing text appear anywhere.
- Layout holds at 375px with no horizontal scrolling.
