Design a dark-mode mobile app interface screen: deep oceanic immersion paired with precision luminescence, guiding visitors through tactile curiosity.
LAYOUT
Mobile-first single-column vertical flow with full-bleed hero artwork in the upper half. The header floats transparently over the image, leading into a left-aligned display headline and side-by-side action triggers. A three-column logistic info banner grounds the hero, followed immediately by horizontally scrolling experience preview cards.
PALETTE (use these exact hex values)
- #040a14 — Canvas Void: Background canvas colour beneath imagery, cards, and system overlays
- #0a1726 — Panel Slate: Base fill for structured informational cards and container frames
- #15263b — Panel Border: Subtle one-pixel stroke enclosing info panels and outline badges
- #4de1fc — Cyan Bioluminescence: Highlights, category tags, active pagination pips, and gradient terminus
- #124ce8 — Royal Cobalt: Gradient start for primary CTA and strong brand accents
- linear-gradient(90deg, #1041c9 0%, #0088cc 60%, #1ab8df 100%) — Button Gradient: Primary interactive action button fill across hero screens
- #ffffff — Text Primary: Hero display headlines, active values, button labels, and icons
- #8da1ba — Text Muted: Body copy, subtitles, secondary metadata labels, and inactive pips
TYPOGRAPHY
Typeface SF Pro Display (or Inter, Plus Jakarta Sans, Roboto), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 15px body, 17px subheading, 22px heading, 34px display. Tracking -0.02em at display, 0.08em at small caps. The typography is technical yet accessible, evocative of contemporary science centres and high-end cultural institutions. Clean geometric grotesque letterforms communicate scientific authority while generous tracking on captions creates an editorial polish. Standard system fonts like SF Pro or Inter reproduce this precision seamlessly.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 14px, buttons 16px. Spacing on a 4px unit, 16px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is created purely through luminous optical layering rather than box-shadow drops. Surfaces rise out of the dark backdrop via deep naval slate tints, hairline strokes in #15263b, and rim-lit photographic subjects. Interactive elements glow subtly through saturated gradient fills against pitch backgrounds.
IMAGERY
Photography is cinematic, highly atmospheric, and dramatically lit from above, mimicking underwater or theatrical spotlights. Content depicts monumental engineering, scale models, and robotics with high-contrast specular highlights. Muted, flat editorial or cartoonish stock imagery is strictly prohibited.
SIGNATURE DETAIL — the thing that makes this design itself
The vertical transition from deep caustic sea lighting down into a structured tripartite logistics pod, bridged by a horizontal cobalt-to-cyan pill button. Misusing this involves removing the gradient or replacing the unified multi-column info card with disjointed separate boxes.
MUST
- Use full-bleed photographic hero art that naturally dissolves into the #040a14 canvas.
- Style section kickers in cyan uppercase with tracked letterspacing (approx 0.12em).
- Keep key logistics data grouped inside single-stroke segmented cards with hairline vertical dividers.
- Retain generous corner radii (16px to 20px) on interactive cards and major buttons.
AVOID
- Do not introduce sharp card corners; avoid anything under 12px radius.
- Never use pure black (#000000); always tint dark backgrounds with cool navy hues (#040a14).
- Avoid flat, low-contrast solid grey buttons for primary intents; use the signature blue-to-cyan gradient.
- Do not drop horizontal rules or thick dividers between content tiers; rely on dark negative space.
