Theming

Styles are the visual aspects of a UI that give it a distinct look and feel. They can be customized by changing your Material theme.

Color scheme

A color scheme is the group of key color tones assigned to specific roles that get mapped to components.

Tokens

A color scheme can be set using CSS custom properties.
