Design a dark-mode mobile app interface screen: deep midnight canvas illuminated by luminous data glows and precision fintech telemetry.
LAYOUT
The layout is a single-column mobile feed engineered around a strict 16px horizontal viewport inset. Top-down order begins with a lightweight navigation bar, cascades directly into an expansive portfolio balance card with integrated action buttons, follows with an accounts carousel, and anchors on a comprehensive spending analytics breakdown card. Vertical pacing relies on standard 24px margins between logical modules.
PALETTE (use these exact hex values)
- #060B11 — Canvas Midnight: deepest background surface across the entire mobile screen viewport
- #0E1520 — Surface Card: elevated card fill providing visual containment for overview metrics and charts
- #131C2A — Surface Subcard: secondary nested containers such as account chips and action button states
- #1C2636 — Card Border: subtle hairline contour defining container perimeter without high-contrast friction
- #2F68F6 — Cobalt Primary: dominant action tint, active button border, sparkline stroke, and housing category
- #22C55E — Gain Emerald: positive delta metrics, unread notification pip, and dining category allocation
- #E0872A — Amber Transport: transport segment in spend breakdown and credit card icon backdrop
- #9E58F6 — Amethyst Shopping: shopping segment in spend breakdown and auxiliary analytical highlights
- #FFFFFF — Text Primary: high-emphasis values, titles, balances, and critical readouts
- #8493A8 — Text Muted: metadata labels, inactive icons, section subtitles, and percentage breakdowns
TYPOGRAPHY
Typeface SF Pro Display (or Inter, Plus Jakarta Sans), weights 400/500/600/700. Sizes 12px caption, 13px body-sm, 14px body, 15px body-lg, 17px subheading, 20px heading, 32px display. Tracking -0.03em at large numeric display, 0em at body. The typography communicates institutional-grade fintech precision through an uncompromising, neutral neo-grotesque sans-serif. Numbers dominate the visual weight with bold weights and tight tracking, ensuring large figures read immediately as authoritative telemetry. When reproducing, use Apple's native SF Pro Text/Display or Google Fonts Inter to preserve the exact geometric stability.
GEOMETRY & SPACING
Corner radii — cards 20px, links 999px, inputs 12px, buttons 14px. Spacing on a 4px unit, 12px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is rendered flatly through surface layering rather than cast shadows. Background planes sit at #060B11, rising to #0E1520 on level 1 cards and #131C2A on level 2 buttons. Visual boundaries are crisp, defined entirely by 1px solid borders in #1C2636 and luminous vector glows directly on stroke paths.
IMAGERY
This interface avoids raster photographic assets entirely, adopting an exclusively vectorized telemetry visual language. Financial states are communicated via glowing smooth bezier sparklines, multi-colored SVG ring arcs, and minimalist 2px line icons housed within colored tint containers. Photographic imagery would shatter the clean, high-precision instrument aesthetic.
SIGNATURE DETAIL — the thing that makes this design itself
The signature element is the dual-tone Hero Portfolio Module, which merges a large telemetry display with an embedded vector sparkline glowing from cobalt to mint, sitting directly above a row of self-contained quick-action pill buttons. This establishes total command of top-of-funnel wealth monitoring before diving into granular ledgers.
MUST
- Keep all main surface panels consistently at 20px border radius with 1px border #1C2636.
- Use semantic green (#22C55E) exclusively for positive performance metrics and system alerts.
- Reserve vibrant electric cobalt (#2F68F6) for interactive affordances and key line charts.
- Render large currency amounts with tight letter tracking (-0.03em) to ensure numeric solidity.
AVOID
- Never use pure black #000000; the canvas relies on atmospheric dark blue-slate tone.
- Do not drop heavy, diffused drop shadows; separate planes via 1px border #1C2636 and subtle fills.
- Avoid colored backgrounds for entire cards; keep colors localized to charts, glyphs, and strokes.
- Never set secondary metrics in pure white; keep metadata strictly within #8493A8.
