Space Grotesk typography. warm cream paper background with one electric cobalt blue accent. Best for B2B SaaS pitch, consulting deliverable, internal review. AI-ready design system. The pairing of cobalt blue with cream paper stock isn't arbitrary — it's a direct lineage from mid-century Swiss corporate identity. When Müller-Brockmann and his contemporaries were building visual systems for banks and insurance firms in the 1950s, they understood something fundamental: authority doesn't need to shout. The deep blue carried institutional weight while cream softened the Germanic rigidity that pure white imposed. This combination survived the digital transition better than most because it solves a real problem. Pure white screens at 300+ nits are hostile. Cream backgrounds reduce perceived contrast without sacrificing legibility, and cobalt provides enough chromatic punch to establish hierarchy without the visual noise of a broader palette. It's the typographic equivalent of a well-tailored navy suit — nobody questions it, nobody remembers it specifically, but everyone trusts it. The minimalist constraint here isn't aesthetic preference — it's strategic. Professional services sell expertise, not personality. Every decorative element you add is a potential objection, a reason for a conservative buyer to hesitate. The Swiss understood this: reduce until only the message remains. - Density: 5/10 — Balanced - Variance: 6/10 — Dynamic - Motion: 4/10 — Subtle - **Style:** Clean, Professional, Restrained, Modern - **Keywords:** Clean professional, cobalt blue, cream paper, single accent, restrained, SaaS, modern sans, trustworthy - **Era:** 2020s Corporate - **Light/Dark:** ✓ Full / ✗ None ## Colors - **Bg** (#FDFAE7) — Primary surface or dominant color - **Primary** (#1E2BFA) — Accent highlight, links and focus states - **Text** (#111111) — Secondary accent - **Text Muted** (#6B6B6B) — Accent color, emphasis elements ## Typography - **Display / Hero:** Space Grotesk — Weight 700, tight tracking, used for headline impact - **Body:** Inter — Weight 400, 16px/1.6 line-height, max 72ch per line - **UI Labels / Captions:** Inter — 0.875rem, weight 500, slight letter-spacing - **Monospace:** JetBrains Mono — Used for code, metadata, and technical values Scale: - Hero: clamp(2.5rem, 5vw, 4rem) - H1: 2.25rem - H2: 1.5rem - Body: 1rem / 1.6 - Small: 0.875rem ## Layout - **Grid:** CSS Grid primary.
