Design a dark-mode web interface screen: glowing isometric glass floating within a deep obsidian developer cockpit.
LAYOUT
The workspace uses a persistent 240px sidebar on the left containing the brand mark, navigation links, and account telemetry. The main viewport opens with a hybrid marketing-onboarding hero (headline, CTAs, and 3D device artwork) stacked above a 4-column metric KPI strip. The lower tier splits into an asymmetrical grid featuring a recent projects data table on the left (45% width) and a dense build activity histogram on the right (55% width).
PALETTE (use these exact hex values)
- #020612 — Obsidian Base: deep background canvas behind the entire application shell
- #070E1E — Navy Surface: fill colour for all primary dashboard cards, sidebar, and floating modules
- #132038 — Surface Border: fine structural stroke delimiting cards, inputs, and dividers
- #00A3FF — Electric Cyan: primary brand callout, active links, primary CTA fill, and hero gradient start
- #6366F1 — Neon Violet: hero gradient text terminus and secondary isometric element accents
- #10B981 — Mint Emerald: success badges, positive delta percentages, and metric trend lines
- #EC4899 — Crimson Pink: failed build status indicators and negative metric deltas
- #FFFFFF — Bright White: primary headings, prominent numbers, and high-emphasis button labels
- #8899B5 — Cool Slate: supporting text, table column headers, and unselected navigation items
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans, SF Pro Display), weights 400/500/600/700. Sizes 11px caption, 12px body-sm, 14px body, 16px body-lg, 20px subheading, 28px heading, 40px display. Tracking -0.02em at display, 0 at body. The typographic tone is ultra-precise, modern, and developer-centric, leaning into the clean geometric neutrality of Inter or Plus Jakarta Sans. Tight letter-spacing on display sizes (-0.02em) provides authority, while generous line heights at small sizes ensure code snippets and micro-metadata remain effortless to scan. System font stacks such as SF Pro or Helvetica Neue serve as acceptable fallbacks.
GEOMETRY & SPACING
Corner radii — cards 14px, links 6px, inputs 8px, buttons 10px. Spacing on a 8px unit, 16px gaps, 32px between sections, 1440px container, comfortable density.
DEPTH
Depth is created purely through luminescence and stroke definition rather than traditional skeuomorphic shadows. Cards sit slightly elevated above the canvas using a border stroke (#132038) against the deep navy fill (#070E1E). Floating elements like tooltips and 3D isometric layers project faint, diffuse glows of cyan and violet.
IMAGERY
Visual assets consist of hyper-clean, glossy isometric 3D illustrations floating over dark geometric planes. Devices, gears, code blocks, and micro-figures glow with neon cyber-blue and magenta light reflections. Flat lifestyle photography or standard stock illustrations are strictly forbidden.
SIGNATURE DETAIL — the thing that makes this design itself
The dual-tone electric cyan-to-violet gradient text headline ('mobile experiences') paired with an adjacent floating isometric glass 3D device stage. This establishes immediate technical authority by merging consumer-grade visual polish with rigorous developer-dashboard utility. It is misused when copied onto busy, bright backgrounds where the neon luminescence loses its optical contrast.
MUST
- Use electric cyan (#00A3FF) exclusively for primary interactions, active nav states, and critical data bars.
- Apply fine 1px strokes (#132038) around dark cards to guarantee legibility against the pure obsidian backdrop.
- Maintain high typographic contrast: use pure white for key values and #8899B5 for supporting contextual labels.
- Ensure status indicators combine a semantic colour dot with explicit text labels for accessible feedback.
AVOID
- Do not introduce light grey backgrounds or white cards anywhere; the system is strictly dark-mode.
- Do not use drop shadows with dark blurs; depth is produced strictly by subtle border outlines and glowing fills.
- Do not mix rounded pill buttons with sharp rectangular cards; maintain 10px-14px harmonized corners.
- Do not use saturated yellow or orange accents; stick strictly to cyan, indigo-violet, emerald, and hot pink.
