Struct SchemeRainbow 

pub struct SchemeRainbow { /* private fields */ }

A rainbow color scheme creating a spectrum-inspired color palette.

Generates colors distributed across the full hue range with high chroma and a tertiary shift. Best for playful, colorful designs.

Example

use mcu_scheme::SchemeRainbow;
use mcu_hct::Hct;

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

Implementations

impl SchemeRainbow

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

Create a new rainbow 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 rainbow 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)
