Design a dark-mode mobile app interface screen: deep slate obsidian banking energized by high-frequency mint luminescence and tactile floating cards.
LAYOUT
The screen follows a strict single-column mobile flow bound by 16px lateral screen margins. The sequence begins with the utility header, leads into an asymmetric hero section balancing text and a tilted 3D asset, immediately resolves into a symmetrical 4-column action grid, drops into a horizontal contact carousel, and finishes with modular promotional lifestyle cards.
PALETTE (use these exact hex values)
- #070b0e — Obsidian Ground: Deepest canvas background behind all views and navigation bars
- #10171d — Slate Module: Background fill for action tiles, section cards, and floating panels
- #1a2530 — Border Subtle: 1px hairline borders delineating cards and icon button bounds
- #52d89c — Electric Mint: Hero accent words, primary action pill fill, sparkline strokes, and active links
- #0a2e38 — Atmosphere Cyan: Soft ambient background glow behind the phone graphic and hero section
- #ffffff — Pure White: Primary headings, numbers, avatar names, and critical currency metrics
- #8597a6 — Muted Slate: Supporting descriptions, field subtitles, and unselected status labels
- #122c2d — Deep Teal Container: Background fill for circular icon action buttons like the new contact trigger
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, SF Pro Display, Manrope), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 20px heading, 28px display. Tracking -0.03em on display headers, 0 on small captions. The typographic tone is ultra-modern, crisp, and European-fintech authoritative. Using a geometric sans with slightly tightened tracking at large scales, it conveys institutional precision without feeling dated or overly corporate. If Plus Jakarta Sans is unavailable, Inter or Apple's SF Pro Display serve as exact structural drop-in replacements.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 14px, buttons 999px. Spacing on a 4px unit, 12px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is created entirely through optical layering and atmospheric luminance rather than traditional black drop shadows. Surfaces elevate from canvas (#070b0e) to card level (#10171d) via subtle tone shift and 1px borders (#1a2530). True height is expressed through radial gradient glows—such as the soft teal bloom behind the hero smartphone—and glass-morphism specular highlights inside graphic cards.
IMAGERY
Photography is restricted to crisp circular portrait crops of individuals under natural, warm studio lighting, grounded by neutral backgrounds. Hardware imagery relies on matte, hyper-refined device mockups displaying custom neon telemetry UI. Unstyled stock photos, raw illustrations, or cartoony vector icons are strictly prohibited.
SIGNATURE DETAIL — the thing that makes this design itself
The design's unmistakable hallmark is the juxtaposition of an ultra-dark navy-obsidian substrate with focused neon-mint sparklines and typography ('with clarity'). This luminous mint sparkline instantly commands attention and anchors the visual identity. It is misused if spread indiscriminately across every icon or card background rather than reserved for key financial metrics and high-priority action points.
MUST
- Reserve solid mint green #52d89c strictly for primary interactive CTAs, vital indicators, and intentional headline emphasis.
- Maintain consistent 20px corner radii on all major surface panels and section groupings.
- Pair pure white #ffffff numeric values directly above or beside muted slate #8597a6 labels for clean hierarchy.
- Apply subtle 1px borders (#1a2530) to separate dark slate cards against the black canvas.
AVOID
- Do not use generic saturated blue or bright yellow accents; the palette must remain strictly obsidian, teal, and mint.
- Never drop raw drop shadows on dark backgrounds; rely instead on subtle surface borders and colored atmospheric glows.
- Avoid square or sharp 90-degree corners anywhere in the mobile experience.
- Do not make card backgrounds pure black (#000000); always retain the subtle cool navy tint (#10171d).
