Design a light-mode web interface screen: air-cushioned corporate clarity rendered in porcelain whites, razor-thin lines, and pure cobalt accents.
LAYOUT
The workspace utilizes a fixed 240px vertical sidebar on the far left, offset by a fluid multi-column executive canvas. Content flows from a global utility header (search and profile) into a top row of four equal-width KPI cards. The main body divides into a 2/3 primary charting zone and 1/3 secondary activity feed, followed by a full-width structured data table and bottom-tier multi-metric analytics.
PALETTE (use these exact hex values)
- #F8FAFC — Canvas Background: Global application workspace background behind all floating cards and sidebars.
- #FFFFFF — Card Surface: Pure white background for analytical modules, table containers, and popovers.
- #0066FF — Cobalt Blue: Primary CTA buttons, active sidebar tab indicator pill, and primary chart trend lines.
- #E2E8F0 — Border Subtle: Card bounding borders, horizontal table dividers, and input outlines.
- #0F172A — Text Primary: High-contrast headings, main metric figures, and primary table text.
- #64748B — Text Muted: Labels, secondary descriptions, axis numbers, and inactive navigation links.
- #10B981 — Emerald Success: Positive delta percentages, 'On Track' badges, and profit metric bars.
- #F59E0B — Amber Warning: 'At Risk' tags, secondary timeline activity icons, and warning donut segments.
- #EF4444 — Coral Critical: 'Off track' metrics and severe issue tracking badges.
TYPOGRAPHY
Typeface Inter (or system-ui, -apple-system, Segoe UI), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 13px body, 14px body-lg, 15px subheading, 18px heading, 24px heading-lg, 28px display. Tracking -0.01em at display, 0 at body. The typographic tone is authoritative, institutional, and highly legible, delivered through a neutral grotesque sans-serif like Inter. Heavy weight shifts (from 400 caption to 700 metric displays) create immediate scannability without feeling chaotic. Licensing is straightforward via open-source Google Fonts.
GEOMETRY & SPACING
Corner radii — cards 12px, links 6px, inputs 8px, buttons 8px. Spacing on a 4px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is created almost entirely through subtle surface differentiation and hairline structural boundaries. Cards feature a 1px border (#E2E8F0) and an imperceptible micro-shadow (0 1px 2px rgba(15, 23, 42, 0.04)). Modals and active dropdowns elevate only slightly with soft 4px blur shadows.
IMAGERY
Imagery is strictly utilitarian and human-centric, limited to circular 24px-28px profile photos for project owners and avatar thumbnails. Graphic illustrations are omitted in favor of clean SVG line icons and precise chart paths; skeuomorphic badges or textured backgrounds are prohibited.
SIGNATURE DETAIL — the thing that makes this design itself
The thin-rule bordered metric card containing an unadorned, floating monochrome sparkline nestled beneath large crisp currency typography. To execute properly, ensure the sparkline has zero gradient area fill, rests directly on the card canvas, and scales to exactly 36px in height with a 2px stroke.
MUST
- Use 1px border (#E2E8F0) around all content cards instead of heavy drop shadows.
- Keep sparkline strokes at exactly 2px width with smooth bezier curves.
- Pair every large financial metric (24px-28px) with a subtle comparison baseline label below it.
- Use pill-shaped status tags with transparent pastel backgrounds matching their text hue.
AVOID
- Never use dark, multi-colored gradients behind dashboard cards or panels.
- Do not allow raw table borders to exceed 1px or use darker borders than #CBD5E1.
- Avoid floating elevation shadows larger than 0 1px 3px rgba(0,0,0,0.05).
- Never mix serif or expressive display typography into metrics or table cells.
