Found some content on GitHub: SmartToolFactory/Compose-Extended-Colors: Utility library that expands Compose Colors with Material Design2 colors, color swatches, Material Design 3 Tonal Palettes, color names, and utility functions to convert between HSL, HSV, RGB, HCT models and to HEX or from HEX (github.com)
But I don’t understand the code and don’t know if it’s useful.
