Design a light-mode web interface screen: a pristine clinical dashboard translating critical epidemiological data into crisp, low-cognitive-load diagnostic panels.
LAYOUT
The workspace utilizes a fixed-width dark sidebar on the left (approx 240px) paired with a responsive 12-column grid canvas. The header bar houses page taxonomy on the left and utility date pickers with primary actions on the right. Content descends logically: immediate pulse telemetry (4 KPI cards), followed by mid-tier analytical deep-dives (split 40/60 for symptoms and longitudinal trends), terminating in operational execution panels (tabular reports on the left, alert feed and quick actions stacked on the right).
PALETTE (use these exact hex values)
- #0E1738 — Sidebar Obsidian: structural backdrop for the persistent vertical navigation menu and support panel
- #F7F9FC — Canvas Ice: main application background providing subtle contrast behind floating white data cards
- #FFFFFF — Card Pure White: surface fill for all analytical modules, table containers, and KPI cards
- #3B66F5 — Primary Accent Cobalt: call to action button fill, selected navigation states, and interactive links
- #00BFA5 — Clinical Cyan: recovered status, mild severity badge indicators, and primary symptom progress bars
- #F59E0B — Warning Amber: severe case counters, medium severity indicators, and secondary caution badges
- #F87171 — Critical Coral: alert bell badges, high-severity table flags, and hotspot anatomical markers
- #1E293B — Deep Slate Text: primary headlines, KPI numeric readings, and key table records
- #64748B — Muted Slate Text: secondary metadata, column headers, axis labels, and inactive sidebar links
- #EDF2F7 — Border Subtle: hairline boundary strokes on cards, table rows, and search inputs
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, system-ui), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 15px body-lg, 18px subheading, 24px heading, 28px heading-lg. Tracking -0.01em at display, 0 at body. Plus Jakarta Sans delivers an authoritative yet welcoming clinical precision. Its wide apertures and crisp numeric forms ensure high data fidelity across dense metrics without feeling clinical in an austere sense. Inter or DM Sans serve as drop-in open-source substitutes without altering metric rhythm.
GEOMETRY & SPACING
Corner radii — cards 16px, links 6px, inputs 8px, buttons 10px. Spacing on a 8px unit, 20px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is communicated with extreme subtlety rather than high-contrast shadows. White cards sit on a #F7F9FC canvas bounded by hairline 1px borders (#EDF2F7) with an ultra-diffused shadow (0 2px 8px rgba(15, 23, 42, 0.04)). The only stark contrast occurs structurally between the midnight navy navigation rail (#0E1738) and the crisp, luminous content canvas.
IMAGERY
Vector-based medical infographics are rendered in flat, gentle pastel gradients (such as the soft lilac and periwinkle lung graphic). Icons use clean 1.5px stroke weight geometry inside rounded square or circular pastel badges. Photographic assets are restricted strictly to circular user avatar portraits (36px) within identity headers and footers.
SIGNATURE DETAIL — the thing that makes this design itself
The stylized anatomical lung graphic with interactive symptom hot spots paired directly with delicate horizontal telemetry bars. This move immediately bridges raw epidemiological numbers with human physiological reality, anchoring an otherwise standard SaaS grid into a dedicated healthcare nerve center. Misusing it involves replacing it with a generic bar chart or using photorealistic 3D renders that clash with the UI's flat vector precision.
MUST
- Reserve saturated accent colors strictly for data values, telemetry sparklines, and status badges.
- Maintain uniform 16px border-radius across all card panels for visual harmony.
- Use 1px borders (#EDF2F7) rather than heavy drop shadows to define analytical panels.
- Ensure the sidebar maintains its deep midnight navy (#0E1738) to ground the lighter operational canvas.
AVOID
- Do not introduce pure black (#000000) for text; use deep slate (#1E293B) to avoid visual fatigue.
- Do not apply heavy multi-layered shadows on white cards; keep elevation minimal and border-driven.
- Do not use saturated primary cobalt on non-interactive structural elements.
- Do not remove the anatomical symptom illustration; it provides immediate contextual domain grounding.
