Design a dark-mode mobile app interface screen: deep obsidian surfaces illuminated by soft violet and electric azure gradients with disciplined mobile cards.
LAYOUT
The mobile layout follows a top-down stacked capsule rhythm. A compact header bar anchors the top, immediately succeeded by an expansive hero showcase card containing rich copy and mockups. Beneath the hero, discrete section blocks with rounded 24px frames encapsulate horizontally scrolling cards for benefits and a 4-column carousel for services, ending with a metric preview header.
PALETTE (use these exact hex values)
- #030408 — Void Black: Absolute background behind all modular sections and system status bars
- #0a0e1a — Section Midnight: Container background for grouped functional blocks and cards
- #0f1523 — Tile Elevated: Individual card tile background for inactive services and feature blocks
- linear-gradient(135deg, #2355fc 0%, #763ced 100%) — Electric Indigo Gradient: Hero primary button background and focal accent fills
- #2768fd — Neon Azure: Active stroke highlights, primary dot indicators, and category text accents
- #9c4dfc — Orchid Violet: Featured card borders and secondary gradient terminal highlights
- #f43f5e — Notification Crimson: Notification dot on top app bar header bell icon
- #ffffff — Pure White: Primary headings, card titles, and high-emphasis labels
- #768297 — Muted Slate: Subtitles, descriptive paragraphs, and inactive status indicators
- #192236 — Subtle Outline: Default borders on secondary buttons and inactive feature cards
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans, SF Pro Display, Manrope), weights 400/500/600/700. Sizes 10px caption, 11px body-sm, 13px body, 15px body-lg, 18px heading, 24px display. Tracking -0.02em at display headings, 0.01em at body-sm. The typography employs a pristine, geometric neo-grotesque sans-serif that radiates enterprise technical precision and sleek modernity. Tight tracking on display headlines delivers punchy executive confidence, while open letter-spacing on small captions preserves crisp legibility on dark glass. Inter or Plus Jakarta Sans are the standard open-source matches.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 10px, buttons 12px. Spacing on a 4px unit, 12px gaps, 16px between sections, 390px container, comfortable density.
DEPTH
Elevation is expressed strictly through luminance shifts and selective neon back-glows rather than drop shadows. Surface level 0 is pitch black (#030408), level 1 sections sit at deep navy-slate (#0a0e1a), and interactive cards float at #0f1523. Selected state borders emit an ultra-soft radial glow to simulate phosphor illumination against dark glass.
IMAGERY
Imagery features photorealistic, high-end technical photography showing modern laptops or dashboards engulfed in dark, ambient office environments with rich magenta and cyan reflections. Visuals are treated with dark vignette gradients to merge seamlessly into container backgrounds. Stock photography showing daylight, brightly lit offices, or smiling faces is strictly off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The signature move is the dual-tone neon perimeter stroke applied to selected card tiles (such as the 'Affordable Pricing' and 'Photography' cards). Instead of flat borders or filled backgrounds, active items are outlined with a fine 1.5px violet-to-cyan gradient that makes them look laser-etched into dark acrylic.
MUST
- Use deep #0a0e1a containers with 24px corner radii to partition major content groupings.
- Highlight selected cards with vibrant 1.5px gradient borders in #9c4dfc or #2768fd.
- Keep descriptive body typography constrained to 10px–12px in desaturated slate (#768297).
- Confine heavy gradient fills strictly to primary CTA buttons and active indicator states.
AVOID
- Do not use light gray or pure white backgrounds anywhere in the UI.
- Do not give secondary buttons solid saturated fills; use dark glass with 1px border.
- Avoid harsh high-contrast drop shadows; use soft colored glow diffusion instead.
- Do not drop container corner radius below 16px; generous curves define this aesthetic.
