Design a light-mode web interface screen: deep royal sapphire meets crisp architectural whitespace in a corporate digital agency showcase.
LAYOUT
The page flows vertically through well-demarcated bands: a high-contrast dark hero hosting value proposition on the left and a perspective dashboard mockup on the right; followed by a centered 3-column 'Welcome/Story' block; an 8-item 4-column services grid; an integrated 4-metric gradient bar; and a tabbed portfolio grid showcasing modern device mockups.
PALETTE (use these exact hex values)
- #091a3e — Hero Royal Dark: Deep nocturnal base of the hero background gradient and dark feature cards.
- #0f3c8a — Hero Royal Gradient Mid: Mid-tone saturation layer for the hero background diagonal glow.
- #1967d2 — Brand Blue: Primary action color for buttons, key badge highlights, and circular icon fills.
- #20b2aa — Cyan Accent: Secondary gradient stop on the metrics band and analytical trend lines.
- #ffffff — Page Surface Base: Main light section background below the hero fold.
- #f8fafc — Card Soft Neutral: Default background fill for service grid cards and inactive filter pills.
- #0f172a — Text Primary Dark: High-contrast headings and primary labels on light backgrounds.
- #64748b — Text Muted Grey: Secondary descriptive copy, subheadings, and inactive navigation links.
- #f1f5f9 — Text On Dark: All copy, stats, and badges rendered over dark navy surfaces.
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, system-ui), weights 400/500/600/700. Sizes 12px caption, 13px body-sm, 15px body, 17px body-lg, 20px subheading, 24px heading, 32px heading-lg, 44px display. Tracking -0.02em at headings, 0 at body. Clean, authoritative, and ultra-readable. The modern geometric sans-serif communicates institutional reliability and engineering polish. It avoids whimsical flourishes in favor of balanced letterforms, tight title tracking, and open body spacing for effortless scannability.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 8px, buttons 8px. Spacing on a 8px unit, 24px gaps, 96px between sections, 1200px container, comfortable density.
DEPTH
Depth is handled predominantly through crisp 1px borders and low-opacity ambient shadows (0 10px 25px -5px rgba(15, 23, 42, 0.05)). In the hero stage, elevation is implied by lighting gradients and an angled 3D floating perspective on the dashboard graphic with a soft blue backdrop glow. Light surfaces stay predominantly flat to preserve corporate clarity.
IMAGERY
Imagery is centered on polished, high-fidelity SaaS dashboard mockups, digital product screens, and circular customer profile photos. Visuals are crisp, vector-based, and rendered in authentic UI scales rather than abstract 3D shapes or stock photography.
MUST
- Anchor primary calls to action with intense royal blue (#1967d2) against white or deep navy.
- Maintain strict 3-column or 4-column balanced grid layouts with uniform 24px gutters.
- Use uppercase, letter-spaced 12px captions in primary blue to introduce major sections.
- Give active cards or focus states inverted contrast (dark navy background) to disrupt visual repetition.
AVOID
- Do not introduce sharp 0px corners; maintain consistent 8px to 16px soft radii throughout.
- Avoid multi-colored icon packs; keep icons monochromatic within blue, slate, or white palettes.
- Do not use heavy drop shadows; rely on 1px subtle strokes (#e2e8f0) and soft 12px ambient blurs.
- Never mix serif typefaces into this clean modernist agency aesthetic.
OUTPUT
