Design a light-mode mobile app interface screen: savile row precision tailored for high-performance automotive component curation.
LAYOUT
The mobile layout follows a top-down executive rhythm bounded within an edge-padded 390px mobile viewport. It begins with an airy utility header, cascades into a staggered editorial headline, and lands immediately on an interactive vehicle selector tool. Below this functional anchor, a balanced 3-column trust strip bridges into horizontal product and category carousels characterized by generous 12px column gaps.
PALETTE (use these exact hex values)
- #F9F8F6 — Limestone White: dominant screen canvas providing warm, non-glaring contrast across mobile views
- #FFFFFF — Gallery White: card modules, input wrappers, and elevated floating containers
- #F4F3F0 — Plinth Grey: subtle backing plate for isolated product hardware photography
- #6B1724 — Heritage Oxblood: primary call-to-action fills, headline emphasis, text links, and badge counters
- #191817 — Engine Carbon: editorial headings, category titles, active vehicle spec values, and icons
- #767471 — Piston Pewter: subtitle copy, part quantities, field labels, and secondary trust markers
- #E8E6E1 — Hairline Rule: vertical dividers inside input selectors and very faint perimeter borders
TYPOGRAPHY
Typeface Playfair Display (or Cormorant Garamond, Freight Display, Instrument Serif), weights 400/500/600. Sizes 10px caption, 12px body-sm, 13px body, 15px body-lg, 18px subheading, 22px heading, 32px display. Tracking -0.02em at display sizes. The typography adopts the voice of an elite auction catalog or bespoke coachbuilder. Playfair Display delivers heritage, bespoke craft, and dignity, counterbalancing the oily, industrial reality of replacement motor parts. Inter provides clinical Swiss legibility for tiny part counts, vehicle model codes, and configuration parameters.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 20px, buttons 12px. Spacing on a 4px unit, 12px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is communicated strictly through surface layering rather than cast shadows. Pure white cards (#FFFFFF) float cleanly above the warmer limestone canvas (#F9F8F6), while product cutouts nest inside recessed plaster-tone wells (#F4F3F0). The interface avoids artificial drop shadows, relying entirely on tonal boundaries and crisp silhouette contrasts.
IMAGERY
Photographs are isolated studio catalog cutouts of OEM parts (perforated carbon-ceramic brake discs, adjustable coilovers, LED headlight housings, synthetic oil jugs) illuminated with soft studio light. Components are placed on dedicated pale warm-grey plinths with soft contact ambient occlusion shadows. Never use lifestyle car photography or cluttered mechanics' workbenches.
SIGNATURE DETAIL — the thing that makes this design itself
The juxtaposition of editorial oxblood serif display typography with immaculate, clinical auto-parts hardware cutouts on soft-toned plinths. To implement correctly, reserve #6B1724 exclusively for the search action and the first word of the headline, pairing it against pure white 20px rounded containers. The signature is broken if industrial dark themes, carbon-fiber textures, or racing stripes are introduced.
MUST
- Use Heritage Oxblood (#6B1724) sparingly for singular focal items like primary actions or key heading words.
- Place hardware images strictly as clean cutouts on soft warm-grey (#F4F3F0) background rounded plates.
- Maintain 20px border radius on primary deck containers to preserve an approachable, modern contour.
- Separate inline selector modules with subtle 1px vertical rules (#E8E6E1) rather than heavy borders.
AVOID
- Do not use dark backgrounds, glowing gradients, or saturated neon carbon accents typical of boy-racer tuning apps.
- Never add heavy drop shadows; elevate cards through pure white (#FFFFFF) contrast against #F9F8F6.
- Do not render product hardware against noisy real-world backgrounds like workshops or garages.
- Avoid pill-shaped buttons for primary actions; preserve crisp 12px corner radii on CTAs.
