Design a dark-mode web interface screen: deep navy twilight illuminated by surgical mint-emerald signals for private high-net-worth portfolio oversight.
LAYOUT
The workspace uses a persistent 240px vertical sidebar alongside a fluid multi-column dashboard body capped by a 64px header. The main canvas stacks a personalized greeting above an expansive net-worth area chart, followed by a 4-column quick-balance row. Below, dual-column 50/50 modules organize complex widgets: portfolio donuts pair with top movers, and transaction logs pair with monthly spending bar charts.
PALETTE (use these exact hex values)
- #080c14 — Canvas Midnight: Root page canvas and sidebar background
- #0f1622 — Card Surface: Background fill for all modular insight cards, stats panels, and chart containers
- #151e2e — Elevated Surface: Active time filters, input bars, icon pill backdrops, and secondary buttons
- #1a2536 — Border Subtle: Hairline 1px card perimeters, horizontal dividers, and header borders
- #45c49d — Mint Emerald Primary: Primary CTA button, sparkline strokes, positive percentages, and dominant chart segments
- #5fe0b6 — Soft Jade Hover: Interactive focus states and secondary glow rings
- #eb5757 — Metric Crimson: Negative percentage changes and outgoing expense values
- #f2994a — Accent Amber: Special promotional icons, category tags, and secondary allocation breakdown points
- #f0f4f8 — Text Primary: Primary metric numerals, account titles, and greeting headline
- #8b9bb4 — Text Secondary: Supporting subheads, axis labels, ticker sub-names, and timestamps
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, General Sans), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 20px subheading, 24px heading, 32px display. Tracking -0.03em on displays, 0 on body. Clean, unpretentious, and mathematically precise. The geometric sans-serif communicates institutional credibility and clarity, utilizing tight negative letter-spacing on high-magnitude numbers to avoid visual drift.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 10px, buttons 10px. Spacing on a 4px unit, 16px gaps, 32px between sections, 1440px container, comfortable density.
DEPTH
Depth is rendered flat-layered without soft raster shadows. Visual hierarchy is achieved purely via surface luminance stepping from #080c14 (canvas) to #0f1622 (cards) to #151e2e (interactive pills/inputs), each bounded by 1px borders (#1a2536).
IMAGERY
Photographic elements are limited to circular user avatars in the navigation bar. Iconography is strictly dual-tone or single-tone geometric line art in 16px to 20px sizes, with occasional stylized 3D isometric spot illustrations reserved exclusively for secondary promo cards.
SIGNATURE DETAIL — the thing that makes this design itself
The luminous mint-on-obsidian financial dashboard architecture, characterized by hairline-bordered #0f1622 cards containing glowing #45c49d vector spline charts and donut segments. It fails when the mint tone is applied indiscriminately to non-action elements or when background cards lose their subtle dark-blue tint.
MUST
- Use solid mint emerald (#45c49d) exclusively for positive performance and primary transaction buttons.
- Enforce 1px #1a2536 hairline borders on every card and structural partition.
- Pair bold financial numerals with reduced-size currency signs and muted 11px/12px category labels.
- Keep card background fills consistent at #0f1622 to maintain unified low-contrast depth.
AVOID
- Never use pure black (#000000); maintain the deep navy-tinted canvas hue (#080c14).
- Do not introduce sharp 90-degree corners on data containers, buttons, or avatar frames.
- Avoid high-saturation red fills; restrict negative signals to precise text and micro-indicators.
- Never use heavy drop shadows; rely on 1px borders and surface steps for card separation.
