Building Your Brand Identity

Introduction

Your documents tell a story through their visual presentation. Consistent branding makes your work recognizable, professional, and polished.

The brand_settings() function helps you create and manage a unified visual identity for all your Quarto projects. Whether you’re a research lab, data science team, or individual consultant, brand_settings() ensures your documents maintain consistent colors, logos, and typography.

What Is Quarto Branding?

Quarto 1.6+ supports branding through _brand.yml files, allowing you to centralize:

Project/organization name: Used in document headers
Colors: Primary brand colors and extended palettes
Logos: Large and small logo variants
Typography: Font families, sizes, and styles
Additional styling: Links, code, headings

Flexible Brand Configuration: Two Approaches

froggeR offers two complementary ways to configure your brand, balancing ease-of-use with comprehensive customization. This ensures you can quickly set up core branding elements while retaining full control over advanced options.

Core Elements (Interactive)

The most impactful branding elements are configured through an interactive prompt:

Project/organization name: What appears in document headers
Primary color: Your main brand color (hex format)
Logo - large: Full-size logo for headers
Logo - small: Icon/favicon for compact displays

Advanced Options (Template)

For specialized or advanced branding needs, froggeR provides access to the complete _brand.yml template (gists/brand.yml within the package). This allows direct editing of all available options, including:

Typography: Font families, sizes, weights, styles
Color palette: Secondary, tertiary, and extended colors
Links: Custom link colors and hover effects
Code styling: Monospace fonts and inline code appearance
Headings: Individual heading level customization
Logo metadata: Alt text, links, and sizing parameters

This full template is based on the gists/brand.yml file used internally by write_brand(). A snippet of the template looks like this:

# Example of the full _brand.yml template (gists/brand.yml)
meta:
  name: ""
  # ... other meta options ...
color:
  palette:
    primary: ""
    # ... other color options ...
logo:
  large: ""
  small: ""
  # ... other logo options ...
typography:
  font-family-sans: ""
  # ... other typography options ...
# ... and so on for links, code, headings

To customize these, select ‘Edit the full template for advanced options’ above.

The Interactive Workflow

Where Is Branding Stored?

froggeR stores branding in two locations:

Project-level: _brand.yml in your project directory
- Used by current project only
- Takes precedence over global branding
- Committed to version control
Global: Platform-specific configuration directory
- Linux/macOS: ~/.config/froggeR/_brand.yml
- Windows: C:\Users\<username>\AppData\Local\froggeR\_brand.yml
- Used as default for all new projects
