Design a light-mode mobile app interface screen: refined editorial luxury anchored by dark photography and pastel category pillars.
LAYOUT
The mobile viewport is structured vertically starting with a 420px tall full-bleed hero block holding branding, navigation, and a key mission statement. Below, a soft-cornered overlay sheet introduces a 3-column horizontally scrolling carousel of category cards. Following this is a full-width editorial dark feature card, transitioning immediately to standard section headers like 'Gallery'.
PALETTE (use these exact hex values)
- #F8F9FA — Canvas Off White: Dominant background color for lower content sections and mobile drawer sheet
- #FFFFFF — Card White: Background for carousel category cards, creating subtle lift above canvas
- #0B111E — Midnight Base: Background for secondary feature card and deep photography shadows
- #3A66E8 — Cobalt Blue: Primary action button fill, active pagination dot, and Mares category indicator
- #F2786D — Coral Salmon: Action circle and icon tone for Stallions pillar
- #56C29E — Mint Teal: Action circle and icon tone for Breeding pillar
- #FDF0EE — Pale Coral Wash: Circular icon container background for Stallions category
- #EAF7F2 — Pale Mint Wash: Circular icon container background for Breeding category
- #EEF2FC — Pale Blue Wash: Circular icon container background for Mares category
- #111827 — Charcoal Title: High-contrast headings on light surfaces and main brand header
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Outfit, DM Sans, Inter), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 15px body-lg, 17px heading, 24px heading-lg, 30px display. Tracking -0.02em at display, 0.05em at caps. The typographic tone is architectural and modern, delivered via a polished geometric sans-serif (Plus Jakarta Sans match). It trades traditional serif luxury tropes for clean, contemporary Swiss precision, emphasizing clarity and pedigree. For web implementation, Outfit or Inter work seamlessly as zero-cost replacements.
GEOMETRY & SPACING
Corner radii — cards 16px, links 999px, inputs 8px, buttons 10px. Spacing on a 4px unit, 12px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is created purely through layered surfaces rather than aggressive drop shadows. The pure white category cards (#FFFFFF) sit upon a softly tinted canvas (#F8F9FA) with almost imperceptible ambient diffusion. The lower content area physically tucks over the hero photo with a large 32px rounded top corner mask.
IMAGERY
Photographs are intimate, studio-lit or barn-lit close-ups of thoroughbred horses, emphasizing rich coat texture, muscle tone, and dark wood stalls. Composition deliberately reserves one-third to one-half of the frame as dark negative space for typographic placement. Bright, casual outdoor snapshots or cartoon illustrations are strictly prohibited.
SIGNATURE DETAIL — the thing that makes this design itself
The signature element is the category card triad: three compact, vertical white cards featuring delicate hairline line-art icons set within soft pastel circular washes, counterbalanced by a solid matching accent circle button at the base. Misusing this pattern by turning them into photographic tiles or removing the bottom arrow circles breaks the visual signature.
MUST
- Use deep, high-end equestrian portrait photography with dark negative space for text legibility.
- Pair each category pillar card with its designated pastel background wash and matching solid action circle.
- Round content container sheets with top radii (32px) when overlapping full-bleed hero photos.
- Maintain high contrast by restricting display copy on dark photos to pure white (#FFFFFF).
AVOID
- Do not use sharp 0px corners; maintain fluid rounding from 10px on buttons to 32px on containers.
- Do not use saturated neons or harsh gradients on the category pill icons.
- Never place dark body text directly over un-vignetted, light photographic areas.
- Do not overcrowd category cards; cap card body copy to two lines.
