Design a light-mode web interface screen: precision architectural telemetry balancing obsidian cockpit navigation against crisp, daylight project worksheets.
LAYOUT
The workspace uses a persistent 240px left-hand control rail paired with an expansive fluid main viewport. The main canvas stacks a global utility bar, a project header with inline badge and primary CTA, followed by an underlined horizontal sub-nav. Below, the layout splits into a 2/3 primary column housing telemetry cards, interactive CAD views, charts, and the full task table, alongside a 1/3 right rail dedicated to real-time activity feeds, key documents, and team presence.
PALETTE (use these exact hex values)
- #0B132B — Midnight Sidebar: Anchors primary application navigation and project switcher on the permanent vertical rail.
- #F8FAFC — Canvas Ice: Main application background providing subtle cool contrast beneath elevated white cards.
- #FFFFFF — Pure Card Surface: Background for individual modular cards, data tables, metric tiles, and CAD viewers.
- #2563EB — Cobalt Primary: Primary action buttons, active tab indicators, chart trajectories, and selected CAD states.
- #0F172A — Slate Heading: Top-level page titles, key metric numbers, table row headers, and card titles.
- #64748B — Muted Slate: Field labels, breadcrumbs, timestamps, file sizes, and secondary metadata descriptions.
- #10B981 — Progress Emerald: Completion indicators, positive ROI markers, completed phase donut sectors, and active status tags.
- #F59E0B — Priority Amber: Medium priority alerts, scheduled inspection markers, and pending budget checkpoints.
- #EF4444 — Deficit Coral: High priority badges, budget deficit numbers, and overdue deadline indicators.
- #E2E8F0 — Hairline Border: 1px structural dividers across card boundaries, table rows, and input boundaries.
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, General Sans, SF Pro Display), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 14px body-lg, 16px subheading, 20px heading, 28px display. Tracking -0.02em at display, 0 at body. The typographic tone is authoritative, systematic, and technical. Plus Jakarta Sans (or Inter) provides a neo-grotesque structural clarity that feels reminiscent of modern architectural blueprints and high-finance consoles. Tabular figures prevent layout shifting in live data streams, while precise tight tracking (-0.02em) on display numbers conveys institutional precision.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 8px, buttons 8px. Spacing on a 8px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is created purely through contrasting surface planes and razor-thin borders rather than aggressive drop shadows. The deep navy sidebar recedes into the background plane, while white cards float atop the #F8FAFC canvas with an almost imperceptible border stroke (1px #E2E8F0) and a soft ambient blur (box-shadow: 0 1px 3px rgba(0, 0, 0, 0.04)). Modals and floating tooltips use slightly elevated drop shadows (0 8px 16px -4px rgba(15, 23, 42, 0.12)).
IMAGERY
Visual media consists exclusively of technical CAD architectural schematics, floor plans, and crisp round user profile avatars. Floor plans utilize clean architectural line art with translucent cobalt room fills (#DBEAFE) for active zoning. Photorealistic hero imagery, stock photography, or 3D character illustrations would completely destroy the technical enterprise credibility.
SIGNATURE DETAIL — the thing that makes this design itself
The dual-plane architectural environment: coupling a high-density, midnight-navy vertical control center directly to an interactive blueprint viewport and high-precision tabular financial trackers. Misusing it involves making the sidebar light grey or cluttering the architectural viewer with heavy non-technical UI chrome.
MUST
- Ground the interface with the dark sidebar (#0B132B) while keeping all workspace analytics on pristine white cards.
- Use 16px corner radiuses consistently on all main content containers and analytical widgets.
- Pair every high-level financial number with a small, explicit trend descriptor or target comparison.
- Reserve vibrant cobalt (#2563EB) strictly for primary callouts, active controls, and interactive focus states.
AVOID
- Never apply heavy black box-shadows; rely on 1px borders (#E2E8F0) and ultra-subtle diffuse ambient lighting.
- Do not use saturated background fills behind data cards; cards must stay pure white (#FFFFFF).
- Never mix serif typefaces into this technical dashboard environment.
- Avoid color-coding task priorities with saturated blocks; use delicate pastel fills with colored text instead.
