Design a light-mode web interface screen: private wealth architecture anchored in deep petrol slate, twilight architectural photography, and crisp teal telemetry.
LAYOUT
The screen uses a two-region master structure: a static 240px dark petrol navigation drawer pinned to the left, and a three-column daylight workspace on the right. In the main canvas, the top section pairs a wide two-column architectural hero alongside a compact portfolio metric card. The lower grid divides into a full-width stepper banner, followed by balanced analytical tiles (Performance, Allocation, Watchlist, and Activity) organized in crisp, aligned blocks.
PALETTE (use these exact hex values)
- #F4F6F8 — Canvas Ice: dominant light application canvas hosting all modular dashboard cards
- #FFFFFF — Card Snow: elevated interior card background for finance widgets and list panels
- #0B161B — Obsidian Petrol: full-height primary navigation background and featured banner baseline
- #23948F — Mineral Teal: primary interactive buttons, active tab pill indicators, and positive sparklines
- #0F172A — Midnight Ink: primary heading typography, hero title, and headline currency amounts
- #64748B — Slate Mist: subheadings, metadata labels, timestamps, and chart axis values
- #E2E8F0 — Border Frost: hairline borders for white cards, segmented steppers, and dividers
- #E28B58 — Tangerine Asset: commercial slice on donut allocation and contextual warning badge accents
- #6C5DD3 — Iris Asset: mixed-use slice on donut allocation and portfolio distribution graphs
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, Outfit), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px subheading, 20px heading, 24px heading-lg, 28px display. Tracking -0.02em for large headings, 0 for body, 0.05em for uppercase. Plus Jakarta Sans delivers an authoritative, high-tier private banking presence combined with Silicon Valley crispness. Bold weights handle high-figure wealth sums with razor-sharp tabular clarity, while medium tracking on captions maintains effortless scannability. If substituting, Inter or DM Sans provides adequate structural precision without losing data legibility.
GEOMETRY & SPACING
Corner radii — cards 14px, links 4px, inputs 8px, buttons 8px. Spacing on a 8px unit, 20px gaps, 32px between sections, 1440px container, comfortable density.
DEPTH
Depth is expressed through surface contrast rather than drop shadows. Cards rely on clean white fills set against the soft grey canvas (#F4F6F8) with subtle 1px outlines in #E2E8F0. The only deep layered contrast stems from the solid obsidian sidebar and the cinematic featured asset card.
IMAGERY
Photography focuses exclusively on premium modern architecture captured during the blue hour or dusk. Compositions emphasize structured glass facades, warm ambient interior light spills, and geometric angles. Consumer stock photos, casual lifestyle shots, or daytime suburban buildings are completely off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The asymmetric dark hero billboard: anchoring a high-luminance, clinical white financial interface with an immersive, dark petrol architectural showcase that instantly telegraphs exclusive real estate capital.
MUST
- Reserve solid teal (#23948F) strictly for primary action buttons, positive trends, and selected telemetry.
- Pair dark obsidian (#0C181E) exclusively with the featured property showcase to create an unmistakable editorial anchor.
- Set all financial metrics using tabular figures and strict tight letter spacing (-0.02em).
- Maintain uniform 14px radii across all main dashboard cards to preserve structural cohesion.
AVOID
- Do not apply deep obsidian backgrounds to analytical charts or standard data cards.
- Never use pure black (#000000); use petrol slate (#0B161B) for deep dark areas.
- Avoid harsh multi-colored badges; rely on teal tints and muted slates for status tags.
- Do not omit the dark sidebar in favor of a top navigation bar, which destroys the asymmetric anchor.
