Design a light-mode mobile app interface screen: quiet luxury watch curation pairing alabaster canvas, oxblood accents, and high-contrast editorial serifs.
LAYOUT
The mobile layout follows a top-down editorial rhythm starting with an open 56px branded app bar. The viewport is dominated first by an expansive 24px-radius hero showcase carousel, followed immediately by a horizontal strip of pastel category pods. A standard section header introduces a 2-column or horizontal snap-carousel product grid with consistent 12px card spacing, concluding with secondary collection teasers.
PALETTE (use these exact hex values)
- #FAF8F5 — Alabaster Cream: Global application background setting the warm tactile gallery baseline
- #121214 — Obsidian Hero: Deep rich black surface for the primary featured showcase carousel
- #FFFFFF — Pure Studio White: Crisp background for individual product catalog cards
- #E5EEF5 — Mist Blue Tint: Background container for modern and minimal watch category collections
- #F9F3EA — Parchment Tint: Background container for classic and best-seller watch categories
- #F8ECEF — Blush Rose Tint: Background container for premium and curated editor selections
- #4A1521 — Oxblood Burgundy: Signature action color for hero buttons and notification badges
- #C59B58 — Brass Gold: Editorial micro-eyebrows and active hero carousel pagination indicator
- #1A1817 — Charcoal Espresso: Primary headings, titles, navigation icons, and active currency labels
- #7A7571 — Warm Muted Grey: Product subtitles, descriptions, view-all links, and specifications
TYPOGRAPHY
Typeface Cormorant Garamond (or Playfair Display, EB Garamond, Didot), weights 400/500/600. Sizes 10px caption, 12px body-sm, 13px body, 14px body-lg, 16px subheading, 20px heading, 28px display. Tracking -0.01em to 0.25em on uppercase. The typographic tone is restrained, aristocratic, and discerning, reminiscent of high-fashion publications like Vanity Fair or The Financial Times' How To Spend It. Cormorant Garamond provides classical heritage character with high vertical stroke contrast, while the neutral sans-serif ground the interface in Swiss horological precision. If unavailable, Playfair Display paired with SF Pro provides a functionally indistinguishable substitution.
GEOMETRY & SPACING
Corner radii — cards 16px, links 0px, inputs 8px, buttons 10px. Spacing on a 4px unit, 12px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is created primarily through tonal contrast and photographic framing rather than standard UI dropshadows. The dark hero card uses dramatic low-key studio lighting with real surface reflections to naturally emerge from the warm canvas. White product cards float on the cream background via subtle 1px surface contrast and minimal ambient blur (0px 4px 12px rgba(0,0,0,0.03)).
IMAGERY
Photography consists of hyper-detailed, high-end studio horology captures featuring textured leather straps, brushed stainless steel, and anti-reflective sapphire crystals. Hero images feature cinematic dark-field lighting against volcanic rock or slate, while catalog listings showcase pristine silhouetted watch cutouts with natural contact drop shadows.
SIGNATURE DETAIL — the thing that makes this design itself
The design's signature move is the theatrical high-contrast contrast punch: sinking a brooding, studio-lit dark obsidian card (#121214) with oxblood CTAs into a serene, sun-bleached alabaster canvas (#FAF8F5). It bridges classical Swiss watchmaking prestige with modern mobile fluency. Misusing it means overpopulating the screen with multiple dark containers, which eliminates the hero card's solitary spotlight effect.
MUST
- Use the alabaster tone #FAF8F5 for all primary screens rather than raw default white #FFFFFF.
- Reserve the oxblood tone #4A1521 strictly for primary conversion actions and cart badges.
- Pair Cormorant Garamond display headlines with clean Inter sans-serif for numbers and metadata.
- Maintain generous 24px corner radii on major hero banners to soften heavy visual contrast.
AVOID
- Never use generic pure black (#000000) for copy; always apply charcoal espresso (#1A1817).
- Do not add drop shadows to category cards; distinguish them solely through pastel surface fills.
- Never render product prices or technical spec numbers in serif typefaces.
- Avoid full-width edge-to-edge buttons; maintain compact, tailored pill button proportions.
