}

A dynamic color scheme generated from a source color.

Constructed by a set of values representing the current UI state (such as whether or not it’s dark theme, what the theme style is, etc.), and provides a set of TonalPalettes that can create colors that fit in with the theme style. Used by DynamicColor to resolve into a color.

Fields

source_color_hct: Hct

The source color of the theme as an HCT color

source_color_argb: u32

The source color of the theme as an ARGB 32-bit integer

variant: Variant

The variant, or style, of the theme

contrast_level: f64

Value from -1 to 1. -1 represents minimum contrast, 0 represents standard, 1 represents maximum contrast

is_dark: bool

Whether the scheme is in dark mode or light mode

platform: Platform

The platform on which this scheme is intended to be used

spec_version: SpecVersion

The version of the design spec that this scheme is based on

primary_palette: TonalPalette

Given a tone, produces a color. Hue and chroma of the color are specified in the design specification of the variant. Usually colorful.

secondary_palette: TonalPalette

Given a tone, produces a color. Hue and chroma of the color are specified in the design specification of the variant. Usually less colorful.

tertiary_palette: TonalPalette

Given a tone, produces a color. Hue and chroma of the color are specified in the design specification of the variant. Usually a different hue from primary and colorful.

neutral_palette: TonalPalette

Given a tone, produces a color. Hue and chroma of the color are specified in the design specification of the variant. Usually not colorful at all, intended for background & surface colors.

neutral_variant_palette: TonalPalette

Given a tone, produces a color. Hue and chroma of the color are specified in the design specification of the variant. Usually not colorful, but slightly more colorful than Neutral. Intended for backgrounds & surfaces.

error_palette: TonalPalette

Given a tone, produces a reddish, colorful, color.

Implementations

impl DynamicScheme

pub fn new(options: DynamicSchemeOptions) -> DynamicScheme

Create a new DynamicScheme from options.

Uses spec-versioned palette generation delegates based on the variant and spec version. The delegate handles variant-specific, platform-aware, and dark/light mode adjustments.

Arguments

• options - Configuration for the scheme including source color, variant, contrast level, dark mode, platform, and optional custom palettes.

Returns

A fully configured DynamicScheme with all palettes generated.

Trait Implementations

impl Clone for DynamicScheme

fn clone(&self) -> DynamicScheme

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
