Design a light-mode mobile app interface screen: tactile construction realism meets midnight wireframe architectural precision in an executive mobile enterprise suite.
LAYOUT
The interface proceeds in an alternating rhythm: full-bleed dark hero header with title and video trigger, transitioning into an elevated 24px rounded editorial card with physical prop imagery, followed by a 4x2 utility grid of service squircle tiles, terminating into a dark secondary vision banner peeking from the bottom edge.
PALETTE (use these exact hex values)
- #040914 — Midnight Blueprint: Deep navy base behind the wireframe hero rendering and navigation bar.
- #F4F6FA — Sheet Canvas: Muted grayish-blue background framing the middle content cards and service grid.
- #FFFFFF — Pure Card: Primary surface for interactive feature cards and individual service tile containers.
- #1E5AE6 — Blueprint Core: Hero action pill background, active carousel dot, and structural wireframe tint.
- #EB6A58 — Terracotta Punch: High-priority secondary CTA pill and notification indicator pill dot.
- #0F172A — Steel Navy: Primary headline typography on white surface panels.
- #64748B — Dust Slate: Secondary description text, supporting labels, and inactive carousel pips.
- #EBF3FF — Service Tint Blue: Pastel circular backdrop for project planning and infrastructure service icons.
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, SF Pro Display, Montserrat), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px subheading, 20px heading, 36px display. Tracking -0.03em on display, 0.08em on uppercase labels. The typographic stance is corporate, structural, and meticulously planned. Using Plus Jakarta Sans or a tight Inter cut, the bold display weight conveys immovable industrial trust, while wide-tracked 11px uppercase metadata labels evoke engineering draft specifications.
GEOMETRY & SPACING
Corner radii — cards 24px, links 999px, inputs 16px, buttons 999px. Spacing on a 4px unit, 12px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is created through dramatic container value stacking rather than heavy dropshadows. Crisp white cards sit over a #F4F6FA base with an imperceptible 0 4px 20px rgba(0,10,30,0.04) blur, while dark midnight panels create physical weight at the viewport poles.
IMAGERY
Visual assets alternate strictly between two modes: abstract 3D cyan blueprint wireframes on pitch navy, and hyper-realistic studio renders of pristine white hardhats and architectural rolls. Avoid raw documentary construction site photos with dirt, yellow safety vests, or muddy job sites.
SIGNATURE DETAIL — the thing that makes this design itself
The deliberate collision between a technical, dark CAD wireframe hero and a sunlit, tactile physical hardhat render contained in smooth 24px floating cards. This visual shift bridges abstract engineering intelligence with concrete execution; misusing it by replacing blueprints with standard stock photography destroys the firm's elite engineering identity.
MUST
- Anchor high-level technical positioning with dark midnight navy blueprint containers.
- Use pure white 24px rounded cards for body content to ensure instant readability.
- Pair every action pill with an inline directional arrow to sustain forward momentum.
- Keep service grid icon backdrops within ultra-soft 10% opacity pastel circles.
AVOID
- Do not place low-contrast grey text directly over the dark wireframe hero graphics.
- Never use sharp 0px corners; all surfaces must honor the 16px to 24px radius system.
- Avoid generic flat vector clip art; imagery must look like CAD schematics or 3D physical models.
- Do not mix multiple high-saturation accent colors on a single card container.
OUTPUT
Render as a clean, pixel-crisp UI design at roughly 1280:3840. Flat vector rendering, real legible text, no browser chrome, no device mockup frame, no watermark, no lorem ipsum placeholder blocks. 在 DraPub 中尝试
