Material Color Utilities

Material Design 3 color utilities for Rust, including HCT (Hue/Chroma/Tone), tonal palettes, and dynamic color schemes.

Quick start

Generate a theme from a seed color and query tokens by name:

use material_color_rs::generate_theme_from_color;

let theme = generate_theme_from_color("#39C5BB")?;
let light = &theme.schemes["light"];
let primary = light.get_argb("primary").unwrap();
assert_ne!(primary, 0);

Data model

• MaterialTheme stores colors as u32 ARGB (0xAARRGGBB) for fast access.
• MaterialThemeJson is a hex-string representation intended for import/export.

Feature flags

• iced: enables SchemeColors::get_iced for converting tokens to iced::Color.

Functions

argb_to_hex

Converts an ARGB integer to an uppercase hex RGB string ("#RRGGBB").

argb_to_rgb

Converts an ARGB integer to an (r, g, b) tuple.

argb_to_rgba

Converts an ARGB integer to an [r, g, b, a] array.

argb_to_rgba_f32

Converts an ARGB integer to an [r, g, b, a] float array (each channel in 0.0..=1.0).

generate_theme_from_color

Generates a Material theme from a seed color.

hex_to_argb

Parses a hex RGB string ("#RRGGBB" or "RRGGBB") into an opaque ARGB color (0xFFRRGGBB).
