contrast-checker

A simple Rust-based CLI tool for calculating the contrast ratio between two colours.

Colour contrast ratio is calculated based on WCAG 2.0 guidelines.

Installation

If you have Rust installed, you can run

cargo install contrast-checker

Usage

You can calculate the contrast between two colours by using:

contrast-checker <color1> <color2>

color1 and color2 are entered as either a Hex code without the # (i.e. ffffff) or as a comma separated RGB list (i.e. 255,255,255).

For example:

contrast-checker ffffff 255,255,255
