Design a light-mode web interface screen: crystalline developer console built on airy cerulean gradients and ultra-crisp elevated cards.
LAYOUT
Structured around a persistent left navigation column composed of a primary electric blue icon rail and an adjacent expanded navigation pane. The primary canvas begins with a top universal search and utility bar, followed by a wide hero banner alongside a 4-column metric grid and sprint chart, grounded below by two equal-width modules for Recent Projects and Activity Feed.
PALETTE (use these exact hex values)
- #F8FAFC — Canvas Background: Global application viewport backdrop behind floating card surfaces
- #FFFFFF — Card Surface: Foreground modular card containers, navigation rails, and header banner
- #0066FF — Primary Electric Blue: Primary interactive call-to-actions, active rail states, and key trendline accents
- linear-gradient(145deg, #1E6BFF 0%, #0052E0 100%) — Promo Card Gradient: Used exclusively for the bottom sidebar upsell and feature highlight module
- #10B981 — Success Emerald: Positive trend metrics, completed progress indicators, and healthy system status badges
- #F59E0B — Warning Amber: At-risk project alerts, warnings, and attention chips
- #EF4444 — Critical Coral: Negative trends, errors, and notification badge pips
- #0F172A — Text Primary: Main dashboard headings, numeric metrics, and project titles
- #64748B — Text Secondary: Table column labels, microcopy, timestamps, and subtitles
- #E2E8F0 — Border Subtle: Structural borders delineating cards, table rows, and input surfaces
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans, SF Pro Display, 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 -0.02em for display and headers, 0 for body. The typographic tone is technical, clean, and highly organized. By utilizing Inter with precise tight tracking on headlines and generous line spacing on data tables, the UI communicates operational efficiency. Plus Jakarta Sans or SF Pro Display serve as direct drop-in alternatives without losing character.
GEOMETRY & SPACING
Corner radii — cards 16px, links 6px, inputs 8px, buttons 8px. Spacing on a 4px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is created using a whisper-light approach: 1px subtle borders (#E2E8F0) combined with ambient drop shadows (rgba(15, 23, 42, 0.04) with 8px blur and 2px Y-offset). Surfaces feel crisp and close to the canvas rather than heavily layered.
IMAGERY
Features clean, matte-finish 3D isometric product representations highlighting code windows, cloud nodes, and UI cards in soft blue and white plastic materials. Flat stock photography is strictly reserved for small circular user profile avatars.
SIGNATURE DETAIL — the thing that makes this design itself
The dual-rail sidebar architecture where an electric blue primary icon strip (#0066FF) docks seamlessly against an expanded white sub-navigation menu, anchoring the crisp white card matrix across the soft slate canvas.
MUST
- Use 16px border-radius consistently on all top-level dashboard content cards.
- Pair primary blue (#0066FF) with soft 10% tint fills for active states and badges.
- Render micro metrics with clear directional arrows (↑ or ↓) paired with respective status colors.
- Maintain high tabular readability by styling column headings in 11px uppercase or muted slate.
AVOID
- Do not use dark, heavy drop shadows; depth must rely on 1px borders and soft 4px blur shadows.
- Do not apply fully saturated red or green fills to entire cards; keep alerts isolated to badges and text.
- Avoid sharp 0px corners anywhere in the interface.
- Do not omit owner avatars or platform subtext in the recent projects data list.
OUTPUT
