Themes

DAC includes a theme system based on design tokens. Choose a built-in theme or define your own.

Built-in Themes

Theme	Description
bruin	Light theme (default)
bruin-dark	Dark theme

Set the theme in your dashboard:

name: My Dashboard
theme: bruin-dark

Or via the CLI:

dac serve --template bruin-dark

The --template flag overrides the theme for all dashboards.

Custom Themes

Create a YAML file with your theme tokens:

name: corporate
extends: bruin

tokens:
  background: "#FFFFFF"
  surface: "#F8F9FA"
  accent: "#0066CC"
  text-primary: "#1A1A1A"
  text-secondary: "#6B7280"
  border: "#E5E7EB"

Use it:

dac serve --template ./themes/corporate.yml

Or reference it in your dashboard:

name: My Dashboard
theme: ./themes/corporate.yml

Token Reference

Themes use CSS custom properties prefixed with --dac-*. The tokens you define in YAML are mapped to these variables and applied to the frontend.

Theme Directory

Place theme files in a themes/ directory alongside your dashboards. DAC discovers them automatically and makes them available by name:

dashboards/
├── sales.yml
├── charts.yml
└── themes/
    ├── corporate.yml
    └── minimal.yml

dac serve --template corporate

Runtime Theme Switching

The dashboard viewer includes a theme toggle in the UI that switches between light and dark modes. The --template flag sets the initial theme.
