Design a light-mode web interface screen: crystalline fintech dashboard balancing cobalt energy cards against soft porcelain modular cards.
LAYOUT
The page is organized into a persistent three-column layout. A fixed 240px navigation sidebar anchors the left, an expansive central section houses the greeting, action triggers, KPI cards, and two primary data modules (transactions and bar chart), and a 280px right-hand rail contains quick actions, account balance donut breakdown, and recent notifications. Visual hierarchy flows naturally from top-left greeting downward into primary metrics and operational logs.
PALETTE (use these exact hex values)
- #F8FAFC — Background Canvas: Global application page background underpinning all modular panels and sidebars
- #FFFFFF — Surface Card: Foreground container fill for dashboard widgets, sidebars, and elevated blocks
- #0066FF — Electric Cobalt: Primary brand anchor, active tab markers, prominent action cards, and bar charts
- #EFF6FF — Soft Blue Tint: Active navigation item backgrounds, secondary button fills, and sparkline fills
- #0F172A — Ink Charcoal: Primary headings, financial metrics, greeting copy, and table numerical values
- #64748B — Slate Muted: Secondary labels, timestamps, table column headers, and subheadings
- #F1F5F9 — Border Subtle: Delicate container dividers, table row lines, and search input borders
- #10B981 — Success Emerald: Positive trend badges, completed transaction pill tags, and success avatars
- #F59E0B — Warning Amber: Pending status badges and warning notifications
- #EF4444 — Danger Coral: Failed status pills, notification counter badges, and negative delta tags
TYPOGRAPHY
Typeface Inter (or SF Pro Text, Plus Jakarta Sans, Roboto), 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 -0.01em at headers, 0 at body. The typographic tone is objective, precise, and approachable. Using a highly legible geometric sans-serif like Inter keeps dense balance numbers and timestamps completely readable without visual friction. Generous weight jumps from 400 regular body text to 600 semi-bold values enforce hierarchy without demanding excessive point-size differences.
GEOMETRY & SPACING
Corner radii — cards 16px, links 6px, inputs 10px, buttons 10px. Spacing on a 8px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is created almost entirely through tonal surface shifts rather than dramatic shadows. Cards sit in pure white (#FFFFFF) on top of the #F8FAFC background canvas, separated by ultra-faint borders (#F1F5F9) or barely perceptible ambient blurs (0px 2px 4px rgba(0, 0, 0, 0.02)). The sole high-elevation element is the promotional sidebar card, which uses vibrant saturation rather than z-index shadows to stand forward.
IMAGERY
Iconography consists of minimal, hairline outline icons (1.5px stroke weight) paired with circular bank brand emblems. The only decorative illustration is a high-gloss 3D isometric representation of credit cards and stacked gold tokens within the lower sidebar promo module. Photographic imagery is confined to circular user avatars in the top header.
SIGNATURE DETAIL — the thing that makes this design itself
The standout signature is the cohesive juxtaposition of the ultra-clean light grid against punchy electric-cobalt highlight moments — specifically the high-saturation primary quick-action tile and matching vertical active navigation indicator. Misusing this means painting multiple tiles in saturated colors, which immediately destroys the visual hierarchy and clutters the interface.
MUST
- Use solid white (#FFFFFF) containers over the #F8FAFC canvas with no hard drop shadows.
- Maintain 16px border radiuses on all main dashboard widget cards.
- Pair electric cobalt (#0066FF) strictly with primary actions, brand badges, and key trend bars.
- Format currency numbers consistently with negative or positive indicators and two decimal places.
AVOID
- Do not introduce deep, murky drop shadows; depth is strictly defined by border tint and contrast.
- Do not use multiple contrasting bright primary colors; keep the palette unified to blue accents.
- Do not reduce body typography below 11px to preserve rapid operational legibility.
- Do not use sharp 0px corners; this design relies entirely on smooth, modern 10px-16px curvature.
