Crate hct_cam16 

hct-cam16 — CAM16 + HCT perceptual color math.

This crate provides a small, dependency-free implementation of:

• CAM16 hue/chroma extraction
• HCT (Hue–Chroma–Tone) color space
• sRGB/Linear RGB/XYZ/L* conversions
• An iterative gamut-mapping solver (Material Design 3 style)

The public API is designed for deterministic u32 ARGB input/output.

Structs

CorePalette

Core tonal palettes for a Material Design 3 style color scheme

Hct

HCT color - Hue, Chroma, Tone

MaterialColorScheme

A complete color scheme (ARGB values).

TonalPalette

A tonal palette generates colors at different tones (lightness levels) while maintaining the same hue and chroma.

ViewingConditions

CAM16 viewing conditions (standard sRGB viewing conditions)

Constants

STANDARD_TONES

Standard tones used in Material Design 3
