Design a light-mode mobile app interface screen: industrial freight logistics rendered through high-contrast nautical darks and warm industrial coral.
LAYOUT
The mobile layout opens with a dark 45% screen-height hero container featuring system status, navigation, H1 copy, CTA, and container graphics. Directly overlapping the hero seam sits a 4-column white freight mode card. Below the seam, a balanced two-column section provides value proposition bullet points on the left and a rounded media carousel on the right, punctuated by pagination dots.
PALETTE (use these exact hex values)
- #081B2E — Midnight Marine: Deep navy background for the hero header, navigation bar, and dark container accents.
- #F7F9FC — Canvas Off-White: Primary mobile canvas background underlying all content cards and scroll areas.
- #FFFFFF — Card Surface: Pure white surface for interactive mode cards, floating modules, and list containers.
- #E85854 — Industrial Coral: High-visibility primary call-to-action buttons and conversion highlights.
- #1D5987 — Oceanic Cobalt: Secondary accent used for circular list badges, metadata pills, and active pagination.
- #EBF2F7 — Ice Blue Tint: Soft neutral fill for icon squircle backgrounds in service navigation.
- #0F172A — Deep Charcoal: Primary headline and title typography on light surfaces.
- #64748B — Slate Muted: Body copy, supporting micro-text, and inactive pagination indicators.
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, SF Pro Display, Manrope), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 15px body-lg, 18px subheading, 22px heading, 28px display. Tracking -0.02em at display, 0.04em at captions. The type selection projects modern industrial efficiency, technical precision, and absolute dependability. Heavy sans-serif headlines convey structural authority akin to high-tonnage transport, while generous line heights in body text ensure quick parsing under field conditions. If Plus Jakarta Sans is unavailable, Inter serves as an exact metric-compatible replacement.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 12px, buttons 10px. Spacing on a 4px unit, 16px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is created primarily through strategic layer overlapping rather than heavy drop shadows. The pure white quick-action card overlaps the dark hero header by 24px, casting an extremely diffuse 0px 12px 32px rgba(8,27,46,0.06) shadow. Secondary elements remain flat against the #F7F9FC canvas to keep scanning speeds fast.
IMAGERY
Photography embraces realistic, high-grade commercial freight assets: container stacks at dusk and gleaming long-haul semi-trucks under natural golden-hour lighting. Hero graphics subtly incorporate a dotted world map silhouette behind the physical shipping containers. Avoid generic cartoon flat illustrations, synthetic 3D renders, or chaotic warehouse clutter.
SIGNATURE DETAIL — the thing that makes this design itself
The distinctive spatial signature is the seamless transition between the dark nautical hero header and the clinical off-white content sheet via the floating 4-column transport mode card. This component anchors the user's eye at the natural thumb-reach zone. Misusing this pattern by turning the mode strip dark or removing its card enclosure ruins the visual balance.
MUST
- Anchor actionable items with warm coral (#E85854) to stand out against heavy navy accents.
- Round all major cards and imagery modules to a cohesive 20px border radius.
- Pair a dark navy hero container with a light canvas body for dynamic depth.
- Keep service mode icons within soft squircle tints (#EBF2F7) rather than harsh outlines.
AVOID
- Do not use harsh 0px sharp corners on content cards or media modules.
- Do not invert the app canvas entirely to dark mode; preserve the light content plane.
- Do not style the primary CTA in blue; reserve blue strictly for informational glyphs.
- Do not crowd the 4-column freight selector; wrap text cleanly under 12px font size.
