Colors

Semantic color tokens map design intent to CSS custom properties. They adapt to light and dark themes and should be preferred over primitive palette values in product code.

Use semantic tokens with var() in CSS or through utility classes documented on the Colors utilities page.

Usage

Reference tokens directly in component styles:

.my-banner {
  color: var(--ro-colors-text-primary);
  background-color: var(--ro-colors-success-light);
  border: 1px solid var(--ro-colors-border-regular);
}

Switch between light and dark themes with [data-ro-mode="dark"] on a root element — semantic tokens resolve to the correct values automatically.
