Design a light-mode mobile app interface screen: crisp morning dew over a lush organic harvest market on clean ivory paper.
LAYOUT
The mobile layout follows a top-down discoverability hierarchy. It begins with an unobtrusive status header containing user greeting and mini-cart, followed immediately by an asymmetrical hero promo banner combining copy on the left and a rich harvest montage on the right. Directly overlapping the banner's baseline sits an elevated 4-item horizontal trust badge container. Below this, repeating horizontal scroll carousels ('Shop by Category', 'Best Sellers') guide browsing with standard section headers and 'View all' alignments.
PALETTE (use these exact hex values)
- #FFFFFF — Canvas White: Primary background for the app body, card containers, and bottom scroll area
- #EBF4EE — Hero Tint Mint: Soft green-tinted hero banner background blending smoothly beneath product photography
- #3B6143 — Forest Green: Primary interactive brand color for CTA button, active indicators, and organic badge accents
- #F1F6F2 — Subtle Sage Tint: Circular icon background fill in the 4-column value proposition banner
- #1E2620 — Deep Forest Charcoal: Primary typography color for major headings, section headers, and bold labels
- #4D7F54 — Leaf Green Accent: Hero heading keyword emphasis ('organic, healthy') and 'View all' action links
- #737D76 — Earthy Slate Gray: Secondary copy including subheadings, value prop descriptions, and greeting subtitles
- #F8FAF8 — Card Surface Gray: Subtle low-contrast background for square category cards and product tile images
TYPOGRAPHY
Typeface Inter (or SF Pro Display,Plus Jakarta Sans,Roboto), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 15px body-lg, 18px subheading, 20px heading, 26px display. Tracking -0.01em at headings, 0 at body. The typography relies on an approachable, modern grotesque sans-serif like Inter or SF Pro Display. Its neutral geometry allows the vibrant food imagery to dominate while bold weights (600 and 700) lend confidence and editorial authority to the health-focused messaging. The selective color change on headline keywords adds warmth and conversational cadence.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 12px, buttons 8px. Spacing on a 4px unit, 12px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is rendered with extreme softness to retain a fresh, airy print catalog feel. The value proposition panel floats slightly above the hero junction using an ambient blur (0px 6px 20px rgba(30,38,32,0.05)) with zero border stroke. Product surfaces and category cards remain completely flat against the canvas, distinguished solely by subtle tonal shifts from #FFFFFF to #F8FAF8.
IMAGERY
Imagery consists exclusively of ultra-crisp, naturally saturated, studio-lit food and botanical assets. Fruits, vegetables, jams, and juices are presented without distracting synthetic packaging, featuring vivid reds, oranges, and greens with soft natural contact shadows. Flat vector clip-art or heavily filtered lifestyle photography is strictly off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The harmonious transition from the pale sage hero header (#EBF4EE) directly into an elevated, curved white trust-badge island that bisects the hero and the category carousel. This creates an organic physical layered effect, signaling freshness and verified quality before any product lists are shown.
MUST
- Use lush, hyper-realistic, isolated photography of fresh produce with gentle cast shadows.
- Keep CTA buttons compact with 8px corner radii and filled in deep forest green #3B6143.
- Pair deep charcoal headings (#1E2620) with muted leaf green (#4D7F54) highlights.
- Wrap multi-feature value propositions into clean white cards with 20px-24px rounded corners.
AVOID
- Never use neon or synthetic greens; stick strictly to organic sage, olive, and forest tones.
- Do not use dark backgrounds for product packshots; keep backdrops pure white or pale sage #F8FAF8.
- Avoid harsh black drop shadows; keep elevation soft with rgba(0,0,0,0.04) blur.
- Do not crowd category items without at least 12px breathing room between icon tiles.
