Design a light-mode web interface screen: deep navy navigation anchoring an ethereal daylight canvas punctuated by playful 3d dimensions and vivid cobalt gradients.
LAYOUT
The viewport is organized into a persistent slim dark sidebar on the far left, followed by a wide single-column content canvas. Content cascades logically: global header at top, split hero banner (type left, 3D artwork right), followed by a consolidated horizontal feature strip, and concluding in a multi-column project grid below.
PALETTE (use these exact hex values)
- #0D1527 — Sidebar Obsidian: Anchors the left navigation rail and hosts high-contrast white and muted blue icons
- #F4F6FC — Atmospheric Canvas: Background base for the main work area, creating gentle contrast against pure white cards
- #FFFFFF — Elevated Surface: Applied to floating feature strips, project containers, search bars, and interactive pill tags
- #2F65F6 — Electric Cobalt: Main call-to-action fills, active navigation states, primary buttons, and hero title accent text
- #0F172A — Navy Charcoal: Dominates high-priority display headers, section titles, and active pill labels
- #64748B — Muted Slate: Secondary descriptors, unselected tab items, inactive navigation links, and input placeholders
- #FA5A47 — Soft Coral: Collaboration category icon tile background and active alert badges
- #22D3EE — Cyan Sky: Creation tool icon tile background and creative project tags
- #34D399 — Fresh Mint: Execution category icon tile background and social content status badges
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Outfit, Inter, Gilroy), weights 400/500/600/700/800. Sizes 11px caption, 13px body-sm, 15px body, 18px body-lg, 22px subheading, 32px heading, 48px display. Tracking -0.03em for headlines, 0 for body. Plus Jakarta Sans conveys a clean, hyper-modern, and optimistic tone well suited for next-generation SaaS tools. Its open apertures and round terminals complement the soft 3D visual language, while heavy bold weights establish clear, authoritative structure against airy whitespace.
GEOMETRY & SPACING
Corner radii — cards 20px, links 999px, inputs 12px, buttons 12px. Spacing on a 8px unit, 24px gaps, 64px between sections, 1440px container, comfortable density.
DEPTH
Depth is created via soft multi-layered shadows on pure white surfaces over a light grey-blue canvas. Key actions use matching colored glows, such as the primary button's electric cobalt ambient reflection, while structural borders are entirely eliminated in favor of luminance separation.
IMAGERY
The visual vocabulary relies on whimsical, matte 3D clay-rendered characters with exaggerated proportions and clean studio lighting. Shapes are organic and friendly—lightbulbs, pencils, and foliage—avoiding hyper-realistic photography or gritty textures entirely.
SIGNATURE DETAIL — the thing that makes this design itself
The standout move is the asymmetric split hero featuring a bespoke 3D conceptual character directly interacting with the oversized headline, highlighted by an energetic brushstroke underline beneath the primary keyword. This deliberate collision of high-polish corporate layout and playful toy-like art instantly removes enterprise stiffness. Misusing it means dropping standard stock vector art in place of coherent 3D character scale.
MUST
- Reserve the Electric Cobalt (#2F65F6) for key calls-to-action and active navigational markers.
- Use generous 20px to 24px border radii on all content containers and white cards.
- Maintain high separation between the deep navy sidebar (#0D1527) and the soft canvas (#F4F6FC).
- Pair heavy display typography with delicate, low-contrast 15px secondary body copy.
AVOID
- Do not introduce sharp 0px or 4px corners into cards or interactive controls.
- Avoid using dark mode inside the main canvas area; contrast depends on the light sheet.
- Do not saturate entire card backgrounds with accent colors; confine them to icon chips and badges.
- Never replace the custom hand-drawn underline accent with a generic straight CSS border.
