Anthropic Brand System

Overview

Anthropic's brand identity is characterized by:

Minimalist aesthetic with clean lines and ample whitespace
Professional, tech-forward visual language
Muted, low-saturation colors avoiding neon or intense gradients
Consistent typography across all materials

This skill provides the authoritative color tokens and design standards for branded artifacts.

Color Palette & Brand Tokens

Primary Colors

Token Name	Purpose	Hex Value	Notes
Anthropic Corporate Dark	Primary container, casing, dark elements	`#1A1A1A`	Deep charcoal; primary dark anchor
Anthropic Identity Light	Background, neutral canvas	`#F8F8F8`	Warm off-white; reduces eye strain
Primary Brand Accent	Interactive elements, connectors, highlights	`#0D47A1`	Deep blue; used for critical UI elements
Secondary Brand Accent	Thermal/mechanical subsystems	`#1565C0`	Medium blue; complementary to primary
Tertiary Brand Accent	PCB, circuitry, digital components	`#42A5F5`	Lighter blue; technical substrates
Muted Mid Gray	Annotation lines, guidelines, secondary text	`#9E9E9E`	Medium gray; 60% opacity for leader lines

Color Application Strategy

Backgrounds: Always use Anthropic Identity Light as the main poster/canvas background
Primary Containers: Use Corporate Dark for outer casings, bezels, and main structural elements
Mechanical Systems: Use Secondary Brand Accent for thermal management, cooling units, mechanical components
Digital Systems: Use Tertiary Brand Accent for PCBs, circuitry, and logic substrates
Interactive Highlights: Use Primary Brand Accent for connectors, ports, and primary interaction points
Annotation: Use Muted Mid Gray (typically 40-60% opacity) for leader lines, dimension lines, and secondary callouts

Saturation & Vibrancy Rules

All colors should be muted and desaturated relative to pure RGB values
Avoid neon, high-intensity, or "AI gradient" styling
Maintain professional, enterprise-grade appearance
Opacity should be used strategically to create hierarchy without saturation increase

Typography Standards

Heading Font

Font Family: Inter (sans-serif)
Weight: 700 Bold
Size: 48-64px for main titles
Letter Spacing: +0.5px for titles
Color: Corporate Dark (#1A1A1A)

Body Text & Annotations

Font Family: Inter or system sans-serif fallback
Weight: 400-500 Regular
Size: 12-14px for annotations
Color: Corporate Dark at 80-100% opacity or Muted Mid Gray for secondary callouts

Font Application Rules

Product Title (e.g., "NOVA"): Use Inter 700 Bold, 56px, Corporate Dark, positioned top-left in a clean heading block
Component Labels: Use Inter 400, 12px, Corporate Dark with 90% opacity
Specification Callouts: Use Inter 500, 11px, Muted Mid Gray with 80% opacity for leader line annotations

Design Principles

Minimalism

Low visual density: Avoid cluttered layouts
Generous whitespace: Let components breathe
Focus through contrast: Not through color intensity
Rule of thirds: Position major elements along compositional thirds

Technical Illustration Style

Exploded views should show clear separation between layers with consistent spacing
Annotation leader lines connect labels to components via thin, subtle lines (Muted Mid Gray, 40-60% opacity)
Avoid drop shadows or 3D effects unless essential for layer clarity
Use flat geometry with clean edges; subtle gradients (if any) should be linear and muted

Brand Coherence

All colors must be applied from the palette above (no custom hex values outside this list)
Typography hierarchy uses size and weight, not color variation
Spacing should follow a 4px or 8px grid system
Opacity is preferred over color desaturation for visual hierarchy

Example: Annotated Exploded View

Background: Anthropic Identity Light (#F8F8F8)
Outer Casing: Corporate Dark (#1A1A1A)
Thermal Unit: Secondary Brand Accent (#1565C0)
PCB Substrate: Tertiary Brand Accent (#42A5F5)
Connector Ports: Primary Brand Accent (#0D47A1)
Leader Lines: Muted Mid Gray (#9E9E9E) at 50% opacity
Title Text: Corporate Dark (#1A1A1A), Inter 700 Bold, 56px
