Design a dark-mode web interface screen: institutional wealth telemetry rendered in dark slate surfaces with bioluminescent cyan charting and disciplined financial legibility.
LAYOUT
The screen uses a two-column asymmetrical layout with a fixed 220px left navigation rail and an expansive multi-tiered main canvas. The top tier features a utility search bar, notification bells, user profile, and page title with action CTAs. Below sits a 4-card metric strip, followed by a 2:1 split between the main performance timeline and asset allocation ring, concluding with a 4-card market ticker strip, full-width holdings table, and a 3-column AI insights footer.
PALETTE (use these exact hex values)
- #0c121c — Canvas Midnight: Deepest canvas background behind the main dashboard grid and viewport gutters
- #0f1622 — Sidebar Navy: Left navigation rail and top header container background
- #131d2b — Card Surface: Modular content card background for metrics, graphs, tables, and insight tiles
- #1e2c3e — Border Slate: Single-pixel stroke dividing cards, table rows, and secondary button perimeters
- #2dd4bf — Bioluminescent Teal: Positive performance vectors, active sparkline strokes, and primary metric callouts
- #147a82 — Deep Teal Button: Fill color for primary action buttons like '+ Add Funds' and 'Upgrade Now'
- #f43f5e — Loss Crimson: Negative delta indicators, downward sparkline paths, and bearish percentage tags
- #f59e0b — Warning Amber: Asset allocation slice for cash and alert icon badge backgrounds
- #f8fafc — Text Pure White: Primary metric numerals, heading labels, and card titles
- #64748b — Text Slate Muted: Table column headings, timestamps, secondary tickers, and card subtitles
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans, SF Pro Display), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 14px body-lg, 16px subheading, 20px heading, 26px heading-lg. Tracking -0.02em at display, 0 at body. The typography is clinical, modern, and disciplined, utilizing a neutral grotesque sans-serif (Inter match) that lets raw digits take precedence over expressive styling. Tight negative tracking on headings (-0.02em) keeps large currency values compact and legible. For open-source replacement, Inter paired with Roboto Mono for table figures delivers an identical institutional feel.
GEOMETRY & SPACING
Corner radii — cards 14px, links 4px, inputs 8px, buttons 8px. Spacing on a 4px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is produced purely through surface luminance stair-stepping rather than diffuse drop shadows. The canvas sits at #0c121c, while cards step forward at #131d2b with crisp 1px strokes in #1e2c3e. Icon badges and popover dropdowns advance further using #1a2536, maintaining an architectural, low-glare darkroom aesthetic.
IMAGERY
This design contains no editorial photographs or raster hero graphics. Visual assets are strictly limited to vector sparklines, clean geometric ring charts, and 28px circular brand mark avatars (Apple, Microsoft, Tesla, Google) on dark roundels. Any decorative photographic imagery would violate the functional terminal ethos.
SIGNATURE DETAIL — the thing that makes this design itself
The design's unmistakable signature is the combination of soft bioluminescent teal sparkline curves sitting directly inside 14px rounded slate containers, anchored by generous numeric typography. It creates an institutional yet approachable private-wealth terminal. Recreate it with a 2px smooth bezier stroke in #2dd4bf over a vertical gradient fill tapering from rgba(45,212,191,0.15) to transparent at the card baseline.
MUST
- Use tabular numbers (font-variant-numeric: tabular-nums) for all currency figures and percentages.
- Limit borders to 1px thickness using #1e2c3e against #131d2b card surfaces for clean containment.
- Color sparkline paths with glowing cyan #2dd4bf for positive gain and crimson #f43f5e for negative decline.
- Maintain consistent 14px border radii on all major widget cards and containers across the board.
AVOID
- Never introduce pure pitch-black (#000000) for card or canvas backgrounds; rely strictly on deep navy-slates.
- Do not apply heavy, blurry drop shadows; depth must be articulated via 1px border contrasts.
- Avoid multi-colored chart backgrounds; sparkline areas must fade into the dark surface via gentle gradients.
- Never set secondary table labels to pure white; keep them anchored in muted #64748b or #94a3b8.
