Design a light-mode web interface screen: precision meteorological telemetry framed in midnight indigo navigation and surgical porcelain cards.
LAYOUT
The workspace uses an asymmetrical two-column application frame: a fixed-width 240px dark left rail paired with a fluid multi-grid dashboard. The top tier features a high-level KPI card row, followed by a primary analytical section split between a large interactive overview map (65% width) and a focused condition snapshot (35% width). The lower tier mirrors this distribution with hourly forecast trends and alert feeds sitting above an expansive tabular registry of monitoring stations.
PALETTE (use these exact hex values)
- #0B1326 — Midnight Sidebar: Primary structural container for vertical navigation and account actions.
- #F4F6FB — Canvas Porcelain: Background canvas behind all content cards and dashboard modules.
- #FFFFFF — Card Pure White: Base surface for all interactive widgets, data tables, and metrics.
- #1D68FE — Cobalt Primary: Primary CTA button background, active nav tab, and focused weather vectors.
- #0F172A — Slate Primary Text: Headings, metric values, station titles, and primary data labels.
- #64748B — Muted Slate Text: Secondary labels, timestamps, units of measure, and placeholder text.
- #E2E8F0 — Border Subdued: Defines boundaries of white cards, search inputs, and table row dividers.
- #EF4444 — Alert Crimson: Severe weather notifications, notification count pill, and critical warnings.
- #F59E0B — Warning Amber: Moderate alert tags, solar indicators, and advisory status items.
- #10B981 — Telemetry Emerald: Active station online indicators and upward trend deltas.
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans, SF Pro Display), 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 headings, 0 at body. The typographic tone is technical, highly disciplined, and dispassionate, prioritizing immediate cognitive parse over stylistic flourish. Inter or Plus Jakarta Sans delivers neutral geometric proportions with legible numerals that prevent visual jitter during real-time data refreshes. All font sizes remain restrained, relying on weight variation (regular 400 to bold 700) to communicate semantic hierarchy.
GEOMETRY & SPACING
Corner radii — cards 14px, links 6px, inputs 10px, buttons 10px. Spacing on a 4px unit, 16px gaps, 24px between sections, 1440px container, comfortable density.
DEPTH
Depth is communicated through architectural surface contrast rather than physical drop shadows. The deep navy navigation rail establishes an anchor layer, while white component cards hover over the pale grayish-blue canvas using a crisp 1px border (#E2E8F0) and an imperceptible, highly diffused ambient shadow (0px 1px 3px rgba(0, 0, 0, 0.04)).
IMAGERY
Visual assets are strictly functional vector iconography and clean 2D graphical representations of meteorological states. Weather conditions utilize refined, flat-color glyphs (sun, clouds, precipitation) without hyper-realistic skeuomorphic textures or photorealistic background photography.
SIGNATURE DETAIL — the thing that makes this design itself
The dual-canvas juxtaposition: a pitch-dark midnight sidebar (#0B1326) abruptly meeting an ultra-clean porcelain white grid (#F4F6FB) populated by soft 14px rounded cards with cobalt and pastel status accents. To preserve this identity, never invert the sidebar to light mode, and ensure metric cards retain their colored rounded icon squares aligned neatly with large tabular numerals.
MUST
- Maintain high contrast between the deep midnight sidebar (#0B1326) and the light dashboard canvas (#F4F6FB).
- Use 14px border radius consistently across all content cards and large modules.
- Restrict bright saturated colors strictly to data states, alerts, and primary focal buttons.
- Set card borders to 1px solid #E2E8F0 to retain clean boundaries on light screens.
AVOID
- Do not introduce heavy black drop shadows; keep elevation flat or exceptionally diffused.
- Never use dark cards within the main porcelain canvas; retain white (#FFFFFF) exclusively.
- Do not color code chart axes arbitrarily; reserve accent hues for specific weather parameters.
- Avoid shrinking data table row heights below 44px to preserve touchscreen and pointer legibility.
