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.
If you have Rust installed, you can run
cargo install --path .
You can calculate the contrast between two colours by using:
contrast-checker <colour1> <colur2>
colour1 and colour2 are entered as a Hex code (i.e. #ffffff) or comma separated RGB list (i.e. 255,255,255). The # for Hex code is optional.
For example:
contrast-checker #ffffff 255,255,255
