Design a light-mode web interface screen: air-brushed cobalt utility, tailored executive metrics bathed in soft ambient daylight.
LAYOUT
The workspace uses a persistent 240px vertical sidebar docked to the left, housing the product mark, vertical navigation links, upgrade banner, and user profile switcher. To its right, the main fluid content panel opens with a compact header row featuring greeting, global search pill, date range picker, and primary CTA. Below the header, data is staged in a strict 12-column grid: a top row of four equal 3-column KPI metric cards, followed by a middle row splitting 7 columns for the spline chart and 5 columns for the projects table, and a lower row splitting tasks, donut chart, and activity logs.
PALETTE (use these exact hex values)
- #F5F7FA — Canvas Background: Outer application background and framing behind cards and navigation sidebar
- #FFFFFF — Card Surface: Modular panel cards, container cards, dropdowns, and search input fill
- #EFF6FF — Active Nav Surface: Subtle light tint for the selected navigation item in the sidebar
- #0066FF — Electric Cobalt: Primary CTA buttons, active sidebar icon/text, prominent chart trendlines, and donut segment
- #0F172A — Deep Slate Navy: Primary metric totals, major titles, card headings, and dark labels
- #64748B — Muted Slate Gray: Secondary labels, chart axes, timestamps, navigation icons, and metadata
- #10B981 — Mint Emerald: Positive delta percentages, revenue sparkline, 'On Track' status pills
- #F59E0B — Sunset Amber: Operating profit sparkline, 'At Risk' status pills, and mid-tier chart segments
- #8B5CF6 — Orchid Violet: Conversion rate sparkline, category icons, and secondary data visualizations
- linear-gradient(135deg, #0052FF 0%, #6366F1 100%) — Banner Gradient: Sidebar promotional CTA banner highlighting 'Upgrade to Pro'
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans,SF Pro Display,system-ui), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 14px body-lg, 16px subheading, 20px heading, 24px heading-lg, 28px display. Tracking -0.02em at headings, -0.01em at body, 0 at micro. The typographical tone is authoritative, corporate, and clean—epitomized by modern grotesque neo-grotesque sans typefaces like Inter or Plus Jakarta Sans. Its tight numerical kerning and tall x-height make financial figures and micro-labels easily scannable across split-second executive glances. If Inter is unavailable, SF Pro Display or Roboto provide suitable drop-in parity without sacrificing data density.
GEOMETRY & SPACING
Corner radii — cards 16px, links 8px, inputs 10px, buttons 10px. Spacing on a 4px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is created through ambient surface contrast rather than obvious shadows. Cards sit upon a cool #F5F7FA canvas, elevated by an imperceptible multi-stop blur: 0 1px 3px rgba(15, 23, 42, 0.04) and 0 6px 12px -2px rgba(15, 23, 42, 0.02). Dropdown panels and active popovers use a slightly deeper shadow (0 10px 15px -3px rgba(15, 23, 42, 0.08)) without adding a physical border.
IMAGERY
The interface avoids photographic illustration entirely in favor of clean, line-drawn Lucide-style iconography and vector geometry. Micro-visuals are limited to rounded company/app glyphs set in pastel tinted squircle containers (e.g. cloud, desktop, phone icons) and a circular 32px user profile avatar in the bottom sidebar. Imagery that is skeuomorphic, hyper-realistic, or 3D would disrupt this flat executive clarity.
SIGNATURE DETAIL — the thing that makes this design itself
The signature element is the horizontal band of four metric summary cards displaying large 24px bold values alongside organic pastel sparklines and matching tinted icon medallions. Misusing this pattern occurs when sparklines are overloaded with dense axis labels or when non-metric data is forced into this compact card ratio.
MUST
- Maintain uniform 16px border-radius across all major dashboard metric and list cards.
- Use 20px padding consistently within cards to preserve balanced whitespace.
- Keep background canvas strictly at #F5F7FA to let white cards subtly detach.
- Use pastel tinted circular backgrounds (28px-32px) behind icons to signal categorization.
AVOID
- Do not use dark or heavy borders; separate surfaces using whitespace and subtle fills instead.
- Do not mix rounded corner radii; avoid mixing 8px and 24px cards on the same grid.
- Do not saturate entire backgrounds with color; keep canvas predominantly pristine white and neutral gray.
- Never display unformatted raw numbers without tabular alignment and currency identifiers.
