Design a dark-mode web interface screen: deep navy modular edtech dashboard radiating precise cyan telemetry and neon wireframe focal points.
LAYOUT
The viewport uses a classic asymmetric SaaS layout anchored by a 240px fixed left sidebar. The remaining viewport spans a three-column asymmetrical main canvas: the left two-thirds handle hero discovery, primary analytics charts, and tabular class data, while the right one-third contains quick action forms, schedule rosters, and notification feeds. Bottom sections resolve into horizontal scrolling cards for deadline triage.
PALETTE (use these exact hex values)
- #060B13 — Canvas Background: deepest foundation canvas covering entire viewport background
- #0D1526 — Card Surface: primary container surface for metrics, forms, lists, and analytical graphs
- #1E2C46 — Subtle Border: 1px structural outline defining card perimeters, table rows, and input fields
- #00A3FF — Electric Cyan: primary brand callouts, active tab indicators, chart curves, and main CTA buttons
- linear-gradient(135deg, #38BDF8 0%, #0077FE 100%) — Cyan Glow Gradient: hero headline secondary line and 3D wireframe ambient backlighting
- #8B5CF6 — Accent Purple: secondary badges, featured pill overlays, and secondary category tags
- #10B981 — Metric Emerald: positive percentage delta indicators and completion status accents
- #F8FAFC — Text Primary: high-contrast titles, metric numbers, and active navigation items
- #94A3B8 — Text Secondary: subtitles, metadata descriptions, input labels, and inactive icons
- #64748B — Text Muted: micro-timestamps, table column labels, and axis markings on charts
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, Roboto), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 18px subheading, 24px heading, 36px display. Tracking -0.02em at display, 0em at body. Plus Jakarta Sans delivers a technical yet approachable modernist voice. The tight geometric letterforms and tall x-height ensure exceptional legibility across dense dashboard data tables and tiny 11px captions. Inter serves as an identical functional substitute without modifying weights or letter-spacing values.
GEOMETRY & SPACING
Corner radii — cards 14px, links 6px, inputs 8px, buttons 10px. Spacing on a 4px unit, 16px gaps, 32px between sections, 1440px container, comfortable density.
DEPTH
Depth is achieved through luminance layering rather than heavy drop shadows. The background sits at deepest #060B13, cards step up to #0D1526 with crisp 1px borders (#1E2C46), and nested inputs or interactive elements rest at #142036. Glowing elements such as chart points and hero assets employ soft radial blurs (0 0 24px rgba(0, 163, 255, 0.25)) for a futuristic neon elevation.
IMAGERY
Illustrations feature glowing 3D wireframe holograms in electric cyan and deep indigo, evoking futuristic telemetry. Embedded media uses rounded photo cards (12px radius) depicting focused learners with subtle dark gradient overlays, augmented by floating frosted badge overlays boasting avatar stacks and rating stars. Flat stock art or hand-drawn cartoon vectors are strictly off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The juxtaposition of deep navy card surfaces (#0D1526) illuminated by radiant cyan (#00A3FF) vector graphs and an ethereal wireframe 3D centerpiece. It communicates high-tech precision in education management. It is commonly misused by applying cyan glow to too many non-interactive elements, creating visual noise instead of clear telemetry.
MUST
- Use #00A3FF sparingly as a deliberate beacon for focus, interactive CTAs, and active chart nodes.
- Enclose all modular content within #0D1526 surfaces with a 1px border in #1E2C46.
- Pair positive numerical deltas strictly with emerald green (#10B981) at 11px font size.
- Maintain 14px corner radii on all card panels for cohesive soft modularity.
AVOID
- Never use pure black (#000000) or flat neutral grays; keep all dark tones tinted with deep navy.
- Do not allow borders to exceed 1px thickness or #2D3E5D in luminance.
- Avoid solid bright card backgrounds; luminosity belongs only on buttons, badges, and lines.
- Never drop card padding below 16px to prevent visual claustrophobia.
