Get an array of rgb values for a color

parseColor.js

// Requires window

const parseColor = (input) => {
    var div = document.createElement('div');
    document.body.appendChild(div)
    div.style.color = input;
    const style = window.getComputedStyle(div);
    const ret = style.color.match(/^rgb\s*\(\s*(\d+)\s*,\s*(\d+)\s*,\s*(\d+)\s*\)$/i);
    document.body.removeChild(div);
    if(ret) {
        return [ret[1],ret[2],ret[3]];
    } else {
        throw new Error(`Error: ${input} could not be parsed.`);
    }
}

console.log(parseColor('rgb(154,22,10)')) // ['154', '22', '10']
console.log(parseColor('#F4C005')) // ['244', '192', '5']
console.log(parseColor('tangerine')) // ['27', '27', '27']
