Calculate a WCAG contrast ratio based on a foreground and background color.
npm install contrast-ratio> Calculate a WCAG contrast ratio based on a foreground and background color
Note: This module only accepts rgb values for simplicity. If you're trying to obtain a ratio for hex,
consider using a helper function/module to first convert your hex strings to an rgb tuple.
``
$ npm i -S contrast-ratio
`js
const ratio = require("contrast-ratio");
ratio([255, 255, 255], [0, 0, 0]);
// -> 21
ratio([0, 0, 255], [255, 255, 255]);
// -> 8.59
