Design a dark-mode web interface screen: midnight observatory for institutional wealth, illuminated by electric mint and ethereal violet data flows.
LAYOUT
The viewport is organized as a persistent left sidebar (approx 240px) coupled to an expansive multi-column dashboard body. The body leads with a utility search and profile header, followed by a personalized welcome title and a 5-column metric KPI strip. The core canvas splits into dense 2-column or 3-column masonry: featured hero investment atop allocation donuts, market charts, tabular watchlists, AI suggestion modules, and a comprehensive client account ledger at the base.
PALETTE (use these exact hex values)
- #080E18 — Canvas Midnight: Deepest canvas background behind sidebar and dashboard viewports.
- #0D1524 — Card Surface: Primary surface fill for modular widgets, metrics cards, and tables.
- #131E33 — Card Elevated: Hover states, nested suggestion cards, and tab pill backgrounds.
- #192438 — Subtle Border: Delicate 1px dividers, gridlines, and card structural perimeters.
- #45E3B8 — Mint Cyan: Primary positive yields, interactive buttons, active tags, and sparklines.
- #8B5CF6 — Nebula Violet: Featured opportunity visual glow, AI insignia, and secondary donut chart segment.
- #F59E0B — Warning Amber: Alternatives asset classification and moderate risk indicator chips.
- #F43F5E — Loss Crimson: Negative delta indicators and downward trajectory sparklines.
- #F1F5F9 — Text Primary: High-emphasis headings, key balance figures, and active navigation labels.
- #94A3B8 — Text Secondary: Subtitles, column headers, secondary timestamps, and muted labels.
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans,SF Pro Display,system-ui), weights 400/500/600/700. Sizes 10px caption, 12px body-sm, 13px body, 14px body-lg, 16px subheading, 20px heading, 24px heading-lg, 28px display. Tracking -0.02em at large numbers, 0.04em at caps labels. The typography is clinical, authoritative, and frictionless. By using a geometric neo-grotesque like Inter with negative tracking at display scales, the interface mimics Bloomberg terminals upgraded for the modern venture-class web. Free substitutes include Plus Jakarta Sans and SF Pro Display, keeping numbers wide, legible, and structurally aligned.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 10px, buttons 8px. Spacing on a 4px unit, 16px gaps, 24px between sections, 1440px container, tight density.
DEPTH
Depth is strictly tonal and flat-hierarchical rather than physical. Backgrounds drop to near-pitch #080E18, while interactive and content-bearing surfaces rise to #0D1524 and #131E33. Edge definition is governed by razor-sharp 1px inner or perimeter borders in muted navy (#192438), augmented only by soft atmospheric radial glows behind strategic AI and featured components.
IMAGERY
Visual imagery is technical, cosmological, and data-driven: glowing 3D particle globes, SVG sparkline trajectories, and crisp vector company marks (Apple, Microsoft, Google). Photographic assets are restricted strictly to circular user and client profile avatars (32px circles). Any generic corporate stock photography, lifestyle imagery, or illustrated flat cartoons would violently break the institutional prestige.
SIGNATURE DETAIL — the thing that makes this design itself
The dual-glow dynamic pairing: sharp electric mint (#45E3B8) functional indicators against an ethereal deep-violet (#8B5CF6) celestial globe hero, housed entirely within midnight-slate containers. Misusing this means applying violet or cyan globally as background washes rather than disciplined, high-value optical points of interest.
MUST
- Use tabular numerals (font-variant-numeric: tabular-nums) across all currency and percentage displays.
- Restrict bright electric mint (#45E3B8) strictly to positive financial deltas, sparklines, and primary CTA triggers.
- Maintain a precise 1px border (#192438) around dark cards to ensure separation without drop shadows.
- Use uppercase 10px tracking (+0.05em) for table column headers and metric subtext.
AVOID
- Never apply high-blur exterior black drop shadows; elevation must be conveyed via border contrast.
- Avoid using bright saturated backgrounds; surfaces must remain deep obsidian (#080E18 to #0D1524).
- Do not mix rounded pill buttons with sharp, squared card corners.
- Avoid using red/green traffic lights for non-financial or decorative accents.
