use-color

Composable primitive color utilities for Rust.

use-color is the color-specific RustUse set for small, composable helpers around RGB values and hex colors. It focuses on lightweight representation and conversion without introducing full palette management or rendering engines.

Scope

• RGB color values
• hex color parsing and formatting
• grayscale checks
• relative luminance for sRGB colors
• named color constants for common base colors

Workspace crates

Crate	Purpose
use-color	Composable primitive color utilities for Rust.

Installation

Crates.io:

[dependencies]
use-color = "0.1"

Local workspace or path dependency:

[dependencies]
use-color = { path = "crates/use-color" }

Examples

Parse and format a hex color:

use use_color::prelude::*;

let color = parse_hex_rgb("#3366CC").unwrap();

assert_eq!(color.to_hex_rgb(), "#3366CC");

Check whether a color is grayscale:

use use_color::prelude::*;

assert!(Rgb::new(80, 80, 80).is_grayscale());
assert!(!Rgb::new(80, 81, 80).is_grayscale());

Measure luminance:

use use_color::prelude::*;

assert!(WHITE.relative_luminance() > BLACK.relative_luminance());

Status

Early v0.1 API.
