'#'+Math.random().toString(16).substr(-6)

[cscty]

Math.floor(Math.random()*16).toString(16)

1. 二进制

function getRandomColor() {
    var color = "#";
    for (var i = 0; i < 3; i++) {
        var sub = Math.floor(Math.random() * 256).toString(2);
        color += ("00"+sub).substr(sub.length);
    }
    return color;
}

2. rgb

function getRandomColor() {
    var r = Math.floor(Math.random()*256);          // 随机生成红色rgb值
    var g = Math.floor(Math.random()*256);          // 随机生成绿色rgb值
    var b = Math.floor(Math.random()*256);          // 随机生成蓝色rgb值

    return "rgb(" + r + "," + g + "," + b + ")";   // 返回rgb(r, g, b)格式颜色 
}

3. hsl

function getRandomColor() {
    var h = Math.floor(Math.random() * 361);
    var s = Math.floor(Math.random() * 101) + '%';
    var l = Math.floor(Math.random() * 101) + '%';

    return `hsl(${h}, ${s}, ${l})`;
}
