Anthropic Brand Color Palette

Core Brand Colors (Official HEX Values)

Token Name	Role	HEX Value	Description
Identity Light	Backgrounds, canvas	`#faf9f5`	Warm off-white, the default background for all brand materials
Corporate Dark	Primary dark / text / casing	`#141413`	Near-black with warm undertone, used for headings, dark UI, device casings
Primary Accent	Interaction highlights, connectors, CTAs	`#d97757`	Warm muted orange, the primary brand accent color
Secondary Accent	Secondary highlights, thermal units	`#6a9bcc`	Muted steel blue, used for secondary visual accents
Tertiary Accent	Tertiary highlights, PCB substrate	`#788c5d`	Muted sage green, used for tertiary visual elements
Muted Mid Gray	Annotation lines, secondary text, dividers	`#b0aea5`	Warm mid-gray, low contrast, for subtle UI elements

Usage Rules

Background: Always use Identity Light (#faf9f5) as the poster/page background unless explicitly overridden.
Dark elements (device casings, heavy borders, heading text): Use Corporate Dark (#141413).
Primary interactive elements (connector highlights, key callouts): Use Primary Accent (#d97757).
Secondary visual accents (thermal management unit fills): Use Secondary Accent (#6a9bcc).
Tertiary visual accents (PCB substrate fills): Use Tertiary Accent (#788c5d).
Annotation leader lines: Use Muted Mid Gray (#b0aea5) at thin stroke widths (1–1.5px).
Avoid: Neon colors, saturated gradients, "AI gradient" styling. All colors are low-saturation and warm-toned.

design_parameters.json Structure

When generating the design_parameters.json file, use exactly these values:

{
  "background_hex": "#faf9f5",
  "corporate_dark_hex": "#141413",
  "primary_accent_hex": "#d97757",
  "secondary_accent_hex": "#6a9bcc",
  "tertiary_accent_hex": "#788c5d",
  "muted_mid_gray_hex": "#b0aea5",
  "applied_heading_font": "Poppins"
}

If Poppins is not available on the system and a fallback is used, update applied_heading_font to the actual fallback font name that was applied (e.g., "Arial").
