Design a light-mode mobile app interface screen: utility infrastructure precision wrapped in dusk photography and pill-soft illuminated cards.
LAYOUT
The screen follows an inverted atmospheric hierarchy. The top 40% is an immersive dark nightscape containing the brand logo, primary claim, and pagination indicators. Centered over the horizon transition sits an elevated white hero card with an oversized product visual. Beneath this anchor, the screen shifts into a bright multi-column utility layout split between feature bullet points on the left and a media preview card on the right.
PALETTE (use these exact hex values)
- #0a111e — Nightfall Navy: Dominant top hero canvas background behind overhead electrical towers
- #ffffff — Pure White: Primary surface for floating hero card and high-elevation containers
- #f6f8fb — Ice Fog: Body background beneath hero section housing secondary listings
- #196cf0 — Electric Cobalt: Primary interactive buttons, key highlights, and active pagination indicators
- #111827 — Charcoal Black: Primary headers and high-contrast titles on light surfaces
- #6b788e — Slate Steel: Subtitles, secondary body copy, and metadata indices
- #34d399 — Mint Shield: Icon container background for best option/value proposition
- #f87171 — Coral Glow: Icon container background for eco/clean energy support badge
- #ff5c38 — Alert Tangerine: Notification pip resting on the top header bell icon
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans,SF Pro Display,Roboto), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 14px body, 16px body-lg, 18px subheading, 20px heading, 32px display. Tracking -0.03em on display, 0.05em on small caps. The typography speaks with authoritative corporate clarity, using Inter-like geometric precision without tipping into sterile neo-grotesque rigidity. Bold 700-weight display titles provide punchy impact while generous line-heights and slight letter-spacing in the uppercase subheaders introduce technical discipline. SF Pro or Plus Jakarta Sans serve as drop-in alternatives without disrupting the modern utility tone.
GEOMETRY & SPACING
Corner radii — cards 24px, links 4px, inputs 12px, buttons 999px. Spacing on a 4px unit, 16px gaps, 32px between sections, 390px container, comfortable density.
DEPTH
Depth is created through dramatic scale overlap and soft atmospheric shading rather than harsh outlines. The main white card hovers across the seam between night sky and pale background with an expansive, low-opacity drop shadow (blur: 32px, opacity: 6-8%). Secondary cards rely on crisp border radii and intense luminance contrast—such as the dark photo thumbnail seated on the pale gray canvas.
IMAGERY
Photography is cinematic, technical, and deliberate: dramatic silhouette shots of transmission pylons against violet dusk skies and moody, close-up macro shots of vintage carbon-filament bulbs. Visuals emphasize electric energy through actual light emission rather than abstract shapes. Any low-fidelity clipart, pastel 3D clay graphics, or corporate stock people would shatter the moody utilitarian aesthetic.
SIGNATURE DETAIL — the thing that makes this design itself
The dual-zone split canvas intersected by an elevated, hyper-radiused white card featuring an illuminated physical bulb within neon electric arcs. It captures electricity as both grand infrastructure and intimate household reliability in a single focal point.
MUST
- Anchor the hero region with moody, high-contrast industrial silhouettes against twilight skies.
- Transition the canvas from nightfall (#0a111e) to daylight (#f6f8fb) behind the primary overlapping card.
- Use pill-shaped contours for all CTA buttons and active pagination markers.
- Emphasize technical credibility with indexed editorial markers like '01 —' and '02 / 05'.
AVOID
- Never use sharp, 0px-corner rectangular cards; always adhere to the 20px-24px rounded aesthetic.
- Do not apply dark backdrops below the primary fold; keep the service breakdown airy and light.
- Never use generic flat illustration when hardware or filament photography can be deployed.
- Avoid warm amber tones for buttons; reserve electric cobalt (#196cf0) strictly for interactive signals.
