Design a dark-mode website section: military autonomy veiled in oceanic midnight hues, sharp telemetry green accents, and tactical maritime aerospace precision.
LAYOUT
Asymmetric hero split: left side houses the technical text block, CTA cluster, telemetry readout stats, and an overlapping submerged drone render along the bottom. The right side features a balanced 2x2 grid of rounded bento cards displaying mission operational use cases. A unified, full-width mission announcement bar anchors the entire composition across the bottom edge.
PALETTE (use these exact hex values)
- #02070e — Abyssal Black: Deep ocean background canvas absorbing all primary views
- #07111c — Subsea Card Surface: Background fill for telemetry modules and use-case image containers
- #162a40 — Naval Stroke: Hairline boundary stroke on cards, buttons, and bottom notification bar
- #22b6ea — Electric Sonar Cyan: Primary action button fill, interactive focus states, and direct links
- #45d677 — Telemetry Green: Live system status dots, radar reticle graphics, and AI pilot markers
- #f8fafc — Pure Signal White: Primary headlines, main numeric metric values, and logo text
- #7e95ad — Contested Grey: Supporting body paragraphs, navigation links, and descriptive captions
TYPOGRAPHY
Typeface Inter (or Geist,SF Pro Display,Helvetica Neue), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 15px body, 18px subheading, 28px heading, 60px display. Tracking -0.03em for headlines, +0.12em for technical labels. The typographic tone is authoritative, defense-grade, and strictly functional. Clean neo-grotesque sizing provides rapid executive scanning, while tight negative tracking on display headings evokes dense industrial engineering. Using Inter or Geist ensures flawless legibility across technical telemetry readouts without feeling ornamental.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 8px, buttons 8px. Spacing on a 8px unit, 20px gaps, 64px between sections, 1440px container, comfortable density.
DEPTH
Depth is rendered organically via underwater atmospheric haze, deep navy background gradients, and hairline boundary strokes (#162a40). Elevated surfaces do not use diffused drop shadows; instead, subtle card fills (#07111c) float naturally against the darker void (#02070e). Key elements like submarine hulls emerge dynamically from background darkness using cyan rim-lighting.
IMAGERY
Photorealistic 3D renders of autonomous submarine drones operating in dark, deep-sea environments with underwater volumetric lighting, sonar rings, and suspended particles. Renders feature heavy maritime textures, naval mines, and deep shelf topography in monochromatic indigo and dark cyan tones. Any daylight, bright tropical water, or recreational marine imagery is strictly prohibited.
SIGNATURE DETAIL — the thing that makes this design itself
The juxtaposition of deep-sea volumetric photography within structured 16px navy bento cards alongside a pulsing green radar telemetry reticle. This conveys uncompromised deep-ocean defense autonomy at a glance. It is broken if replaced with generic SaaS isometric illustrations or bright maritime photography.
MUST
- Ground all imagery in desaturated oceanic depths with realistic sub-surface lighting and blue-grey turbidity.
- Use strict uppercase tracking (+0.12em) for military badges, categories, and technical status pills.
- Limit telemetry green (#45d677) exclusively to active states, radar elements, and online indicators.
- Ensure all card borders use hair-thin 1px strokes in navy slate (#162a40) rather than neutral greys.
AVOID
- Never use warm colors (yellow, orange, red) unless denoting a critical hazard or combat emergency.
- Avoid pill-shaped round buttons for primary actions; preserve the angular 8px defense-spec radius.
- Do not render clean white or bright light-mode surface variations; the theme is permanently nocturnal.
- Never float cards without subtle 1px border lines separating them from the abyssal backdrop.
OUTPUT
Render as a clean, pixel-crisp UI design at roughly 1440:896. 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
