ColorScheme

A set of more than 40 colors based on the Material spec that can be used to configure the color properties of most components. Read more about color schemes in here.

Properties

• error - The color to use for input validation errors, e.g.
• error_container - A color used for error elements needing less emphasis than error.
• inverse_primary - An accent color used for displaying a highlight color on inverse_surface backgrounds, like button text in a SnackBar.
• inverse_surface - A surface color used for displaying the reverse of what’s seen in the surrounding UI, for example in a SnackBar to bring attention to an alert.
• outline - A utility color that creates boundaries and emphasis to improve usability.
• outline_variant - A utility color that creates boundaries for decorative elements when a 3:1 contrast isn’t required, such as for dividers or decorative elements.
• primary - The color displayed most frequently across your app's screens and components.
• primary_container - A color used for elements needing less emphasis than primary.
• primary_fixed - A substitute for primary_container that's the same color for the dark and light themes.
• primary_fixed_dim - A color used for elements needing more emphasis than primary_fixed.
• scrim - A color use to paint the scrim around of modal components.
• secondary - An accent color used for less prominent components in the UI, such as filter Chips, while expanding the opportunity for color expression.
• secondary_container - A color used for elements needing less emphasis than secondary.
• secondary_fixed - A substitute for secondary_container that's the same color for the dark and light themes.
• secondary_fixed_dim - A color used for elements needing more emphasis than secondary_fixed.
• shadow - A color use to paint the drop shadows of elevated components.
• surface - The background color for widgets like Card.
• surface_bright - A color that's always the lightest in the dark or light theme.
• surface_container - A recommended color role for a distinct area within the surface.
• surface_container_high - A surface container color with a darker tone.
• surface_container_highest - A surface container color with the darkest tone.
• surface_container_low - A surface container color with a lighter tone that creates less emphasis than surface_container but more emphasis than surface_container_lowest.
• surface_container_lowest - A surface container color with the lightest tone and the least emphasis relative to the surface.
• surface_dim - A color that's always darkest in the dark or light theme.
• surface_tint - A color used as an overlay on a surface color to indicate a component's elevation.
• tertiary - A color used as a contrasting accent that can balance primary and secondary colors or bring heightened attention to an element, such as an input field.
• tertiary_container - A color used for elements needing less emphasis than tertiary.
• tertiary_fixed - A substitute for tertiary_container that's the same color for dark and light themes.
• tertiary_fixed_dim - A color used for elements needing more emphasis than tertiary_fixed.
