Color

The Color class is similiar to NPM color, but supports calculating color difference (color.delta(other)) and does not need a separate typings package.

Color observer

Utility for detecting the computed character color (the cascading color property) in an element. This is useful for icons that adapt to light and dark themes.

import { ColorObserver } from "@hydroperx/color";
import { useEffect, useRef } from "react";

const ref = useRef<HTMLDivElement | null>(null);

useEffect(() => {
    // color observer
    const color_observer = new ColorObserver(ref.current, color => {
        console.log("light =", color.isLight());
    });

    // cleanup function
    return () => {
        color_observer.cleanup();
    };
}, []);
