Ideal for enterprise, infraestrutura cloud, plataformas corporativas, consultoria tech. AI-ready template. Carbon didn't emerge from a rebrand exercise or a startup's weekend hackathon. It came out of IBM's decades-long struggle with enterprise software that needed to display absurd amounts of data without making analysts want to quit. The system crystallized around 2017 when IBM finally admitted that their sprawling product portfolio—Watson, Cloud Pak, Cognos—needed a shared visual language that could handle density without collapsing into noise. What makes Carbon genuinely interesting is the constraint it was born from: real enterprise environments where a single dashboard might show 200+ data points, where users spend eight hours a day staring at tables, and where "delight" means not getting a headache by 3pm. The 2x grid, the muted cool-gray palette, the obsessive spacing tokens—none of this is arbitrary minimalism. It's information architecture disguised as a design system. Carbon's data visualization library (carbon-charts) deserves particular attention. While most design systems bolt on charting as an afterthought, IBM built theirs from the same atomic tokens. Color sequences are optimized for categorical distinction at scale, not aesthetic pleasure. That's a fundamentally different design philosophy than what you'll find in consumer-facing systems. - Density: 5/10 — Balanced - Variance: 2/10 — Structured - Motion: 4/10 — Subtle - **Style:** Carbon Design System, Enterprise Precision, IBM Plex, Blue-60 Accent, Zero Radius Buttons - **Keywords:** IBM, Carbon, enterprise, IBM Plex, Blue-60, zero radius, bottom-border inputs, 8px grid, token system, flat depth - **Era:** 2024-2026 Enterprise Carbon - **Light/Dark:** ✓ Full / ✓ Full ## Colors - **Azul IBM** (#0f62fe) — Accent highlight, links and focus states - **Branco** (#ffffff) — Light surface, card backgrounds - **Gray 100** (#161616) — Secondary text, borders, muted elements - **Gray 10** (#f4f4f4) — Secondary text, borders, muted elements - **Gray 70** (#525252) — Secondary text, borders, muted elements - **Gray 30** (#c6c6c6) — Secondary text, borders, muted elements - **Azul Hover** (#0043ce) — Secondary accent - **Vermelho** (#da1e28) — Error states, destructive actions ## Typography - **Display / Hero:** IBM Plex Sans — Weight 700, tight tracking, used for headline impact - **Body:** IBM Plex Sans — Weight 400, 16px/1.6 line-height, max 72ch per line - **UI Labels / Captions:** IBM Plex Sans — 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. Max-width containment: 1280px centered with 1.5rem side padding. - **Spacing rhythm:** Balanced. Base unit: 0.5rem (8px). - **Section vertical gaps:** clamp(4rem, 8vw, 8rem). - **Hero layout:** Split-screen (text left, visual right). - **Feature sections:** Zig-zag alternating text+image rows. No 3-equal-columns. - **Mobile collapse:** All multi-column layouts collapse below 768px. No horizontal overflow. - **z-index contract:** base (0) / sticky-nav (100) / overlay (200) / modal (300) / toast (500). ## Elevation & Depth IBM Plex Sans weight 300 (Light) para display — gravitas corporativa com leveza tipográfica. Único acento: IBM Blue 60 (#0f62fe) para tudo interativo. Border-radius 0px em botões primários — retângulos sem suavização. Inputs com bottom-border (não boxed) — padrão Carbon. Profundidade via layering de cor de fundo (branco → gray 10 → gray 20) sem sombras. Grid 2x de 8px com aderência estrita. Token system --cds-* para todas as cores semânticas. Micro letter-spacing (0.16px em 14px, 0.32px em 12px). - **Physics:** Ease-out curves, 200-300ms duration. Smooth and predictable. - **Entry animations:** Fade + translate-Y (16px → 0) over 420ms ease-out. Staggered cascades for lists: 80ms between items. - **Hover states:** Subtle color shift + shadow adjustment over 200ms. - **Page transitions:** Fade only (200ms). - **Performance:** Only transform and opacity animated. No layout-triggering properties. ## Shapes Base corner radius: 0px. See rounded tokens in front matter for the full scale. ## Components - **Primary Button:** Sharp edges (0px) shape. Accent color fill. Hover: 8% darken + subtle lift shadow. Active: -1px translate tactile press. Font weight 600. No outer glows. - **Secondary / Ghost Button:** Outline variant. 1.5px border in muted color. Text in primary color. Hover: subtle background fill. - **Cards:** Sharp edges (0px) corners. Surface background. Subtle shadow (0 2px 12px rgba(0,0,0,0.06)). 1px border stroke. - **Inputs:** Label above input. 1px border stroke. Focus ring: 2px accent color offset 2px. Error text below in semantic red. No floating labels. - **Navigation:** Primary surface background. Active item: accent color indicator. Font weight 500 when active. - **Skeletons:** Shimmer animation matching component dimensions. No circular spinners. - **Empty States:** Icon-based composition with descriptive text and action button. ## Do's and Don'ts - No emojis in UI — use icon system only (Lucide, Heroicons) - No pure black (#000000) — use off-black or charcoal variants - No oversaturated accent colors (saturation cap: 80%) - No 3-column equal-width feature layouts — use zig-zag or asymmetric grid - No `h-screen` — use `min-h-[100dvh]` - No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen" - No broken external image links — use picsum.photos or inline SVG - No generic lorem ipsum in demos - Do IBM Plex Sans weight 300 display - Do Azul #0f62fe único acento - Do Radius 0px em botões - Do Inputs bottom-border - Do Profundidade via cor de fundo - Do Grid 8px estrito - Do Micro letter-spacing - Do Responsivo ## Use Case Enterprise, Infraestrutura cloud, Platforms corporativas, Consulting tech
