Design a dark-mode mobile app interface screen: deep void cinematic immersion shifting into crisp white tactile bookcards on rust dust.
LAYOUT
Vertical mobile stack organized into three clear phases: an immersive 45% viewport cinematic hero with left-aligned typographic hooks, followed by a dense floating white transactional card with two-column book preview and CTAs, culminating in a dark slate biographical profile card anchoring the bottom.
PALETTE (use these exact hex values)
- #0B0E14 — Cosmic Deep Space: Deepest canvas background behind hero cinematic art and astronaut portrait
- #FAFAFC — Card Sheet Surface: High-contrast foreground card containing book details, actions, and metadata
- #E96544 — Martian Rust Accent: Hero play trigger, primary CTA 'Buy eBook', badge background, and active pagination dot
- #131E2E — Deep Midnight Card: Background for the bottom 'About Andy Weir' profile card
- #121A26 — Charcoal Title: Title headings and iconography inside white card modules
- #768194 — Muted Slate Gray: Book blurb descriptions, ratings count, and secondary label metadata
- #FFFFFF — Star White: Hero display text, status bar elements, and author section headers
TYPOGRAPHY
Typeface Inter Display (or Plus Jakarta Sans,SF Pro Display,DM Sans), weights 400/500/600/700/800. Sizes 10px caption, 12px body-sm, 13px body, 15px body-lg, 18px subheading, 22px heading, 26px heading-lg, 38px display. Tracking -0.03em display, 0.08em micro-caps. The typographic voice is authoritative, cinematic, and modern-utilitarian. The contrast between tight, punchy, low-tracking display statements ('Survive. Adapt. Endure.') and technical spaced uppercase metadata echoes scientific spacecraft readouts. Inter Display or SF Pro Display works seamlessly.
GEOMETRY & SPACING
Corner radii — cards 32px, links 8px, inputs 14px, buttons 16px. Spacing on a 4px unit, 16px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is produced through extreme tonal layering rather than fuzzy drop shadows. The pure void background sits at depth 0, over which a crisp, hyper-dense white slab floats at level 1 with sharp perimeter contrast. Secondary dark cards layer on top below, using astronomical line drawings to imply spatial layers.
IMAGERY
Photorealistic, cinematic sci-fi imagery depicting deep-space suits, orbital dust, and Mars landscapes. Lighting must feature crisp cinematic rim lights and high-contrast space illumination. Cartoonish vectors, flat illustrations, or low-res textures would entirely shatter the cinematic prestige tone.
SIGNATURE DETAIL — the thing that makes this design itself
The jarring yet elegant shift from a pitch-black cosmic photograph into a massive 32px-curved clinical white card sheet, bridged by an intense Martian rust accent. If both hero and card shared the same color scheme, the tactile sci-fi book experience would be lost.
MUST
- Retain the strict 32px corner radius on major sheet cards to preserve the fluid tactile contrast.
- Use pure white text over the space background and rich dark charcoal (#121A26) on white cards.
- Keep the signature Martian rust (#E96544) reserved exclusively for focal interactive touchpoints.
- Pair heavy headline weights with uppercase spaced eyebrow labels in tracking ~0.08em.
AVOID
- Do not use generic drop shadows on the white card; separation is achieved purely through extreme luminance contrast.
- Avoid replacing the orange accent with standard blue or green; the rust tone is core brand identity.
- Never shrink card radius below 24px; sharp corners destroy the smooth mobile pebble feel.
- Do not clutter the hero; keep the space suit and planet unoccluded on the right half.
