Struct SchemeTonalSpot 

pub struct SchemeTonalSpot { /* private fields */ }

A tonal spot color scheme emphasizing the source color with tonal adjustments.

Uses the source color as an accent with complementary tones. This is the most commonly used variant and the default for Material Design 3.

Example

use mcu_scheme::SchemeTonalSpot;
use mcu_hct::Hct;

let source = Hct::from_int(0xFF0000FF); // Blue
let scheme = SchemeTonalSpot::new(source, false, 0.0);
assert!(!scheme.is_dark);

Implementations

impl SchemeTonalSpot

pub fn new(source_color_hct: Hct, is_dark: bool, contrast_level: f64) -> Self

Create a new tonal spot scheme.

Arguments

• source_color_hct - The source color in HCT color space
• is_dark - Whether to generate a dark mode scheme
• contrast_level - Contrast level from -1.0 (minimum) to 1.0 (maximum), 0.0 is standard

pub fn with_options( source_color_hct: Hct, is_dark: bool, contrast_level: f64, platform: Platform, spec_version: SpecVersion, ) -> Self

Create a new tonal spot scheme with full options.

Arguments

• source_color_hct - The source color in HCT color space
• is_dark - Whether to generate a dark mode scheme
• contrast_level - Contrast level from -1.0 (minimum) to 1.0 (maximum), 0.0 is standard
• platform - Target platform (Phone or Watch)
• spec_version - Design spec version (2021 or 2025)
