Design a light-mode mobile app interface screen: deep cosmos darkness colliding softly into bright atmospheric planetary light.
LAYOUT
The layout utilizes a top-heavy dark hero block spanning approximately 45% of the viewport, occupied by Mars photography and prominent display typography. A floating 3-column dock overlaps the hero baseline, initiating the transition to a light mode dual-column asymmetric card feed. The rhythm alternates between stacked micro-cards, tall rich media cards, and wide banner-style discovery modules.
PALETTE (use these exact hex values)
- #080C14 — Cosmos Base: Deep night sky backdrop behind the planetary hero header and status bar
- #F8F9FD — Light Canvas: Clean neutral light foundation for content cards and body sections
- #FFFFFF — Card Surface: Floating card background providing maximum contrast and lift
- #FF7B60 — Martian Terracotta: Hero accent color, primary CTA fill, and display text highlight
- #131926 — Midnight Card: Bottom banner card background evoking deep space exploration
- #1B2232 — Ink Slate: Primary high-contrast typography on light cards and body titles
- #768298 — Muted Slate: Secondary descriptive text, body paragraphs, and small captions
- #505488 — Soft Indigo Tint: Subheading tone in light cards and tertiary text accents
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Outfit, Poppins, Inter), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 14px body, 16px body-lg, 18px subheading, 22px heading, 32px display. Tracking -0.03em at display, -0.01em at body. The typographic tone is tech-forward, optimistic, and premium, utilizing modern geometric grotesques like Plus Jakarta Sans. Tight letter-spacing in the display size (-0.03em) lends a modern editorial edge, while balanced body line-heights (1.4–1.5) maintain readability on mobile displays. Poppins or Outfit are suitable zero-cost Google Font alternatives that capture the circular geometric geometry.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 16px, buttons 999px. Spacing on a 8px unit, 16px gaps, 32px between sections, 390px container, comfortable density.
DEPTH
Depth is achieved through dramatic visual overlap rather than heavy skeuomorphic drop shadows. The top white feature dock overlaps the boundary between the dark cosmos illustration and the lower light body, casting a delicate, wide-radius ambient shadow (0px 12px 32px rgba(18,25,38,0.06)). Cutout imagery, such as the bottom astronaut, extends organically to break card boundaries.
IMAGERY
Photography blends photorealistic space exploration subjects—high-resolution planetary surfaces, Mars rovers, and spacesuits—with warm red-orange atmospheric lighting. Illustrations are minimalist line-art emblems encased within tinted pastel circular plates. Heavy cartooning or flat corporate vector art would break the cinematic, high-end prestige tone.
SIGNATURE DETAIL — the thing that makes this design itself
The signature visual device is the planetary light-bleed header that docks directly into a floating triple-column white card widget. This transition blurs the boundary between cinematic dark-mode storytelling and functional light-mode navigation. Misusing it involves placing flat single-tone colors behind the header or omitting the horizontal floating dock overlap.
MUST
- Anchor the hero area with a dark cosmos tone (#080C14) and transition smoothly to crisp light surfaces.
- Use full pill (999px) shapes for all interactive action buttons and badges.
- Pair rich high-contrast dark photography with soft pastel icon backgrounds like #E7DCF8 and #E0F5EE.
- Apply deep terracotta (#FF7B60) intentionally to draw focus to critical hero words and key actions.
AVOID
- Do not use harsh 1px black borders around cards; rely on subtle surface shifts and diffuse shadows.
- Do not use cold pure grey; keep canvas tints subtly blue-shifted (#F8F9FD).
- Never make cards fully sharp or square; corners must stay softly curved.
- Avoid overcrowded button text; keep labels punchy with simple trailing chevrons.
