使用色彩分明的颜色。

它生成了一个视觉上不同颜色的调色板。

Distinct-colors是高度可配置的:

选择调色板中有多少种颜色 将色调限制在一个特定的范围内 限制色度(饱和度)到一个特定的范围 将亮度限制在一个特定的范围内 配置调色板的一般质量

我认为第一个回答是最简洁/有用的，但我只是写了一个初学者可能更容易理解的回答。

function randomHexColor(){
    var hexColor=[]; //new Array()
    hexColor[0] = "#"; //first value of array needs to be hash tag for hex color val, could also prepend this later

    for (i = 1; i < 7; i++)
    {
        var x = Math.floor((Math.random()*16)); //Tricky: Hex has 16 numbers, but 0 is one of them

        if (x >=10 && x <= 15) //hex:0123456789ABCDEF, this takes care of last 6 
        {
            switch(x)
            {
                case 10: x="a" 
                break;
                case 11: x="b" 
                break;
                case 12: x="c" 
                break;
                case 13: x="d" 
                break;
                case 14: x="e" 
                break;
                case 15: x="f" 
                break;  
            }
        }
        hexColor[i] = x;
    }
    var cString = hexColor.join(""); //this argument for join method ensures there will be no separation with a comma
    return cString;
}

正则表达式

总是返回有效的十六进制6位颜色

"#xxxxxx".replace(/x/g, y=>(Math.random()*16|0).toString(16))

令c= "#xxxxxx"。替换(/ x / g, y = > (math . random () * 16 | 0) .toString (16)); console.log (c); document.body.style.background = c

我已经生成了100种不同对比度的不同颜色，你可以根据需要增加数值:

Feedle举例:http://jsfiddle.net/zFbfE/29/ -

// CHANGE THE INITIAL SEED HERE
Math.seed = 23;

/**
 * Math.seededRandom()
 *
 */
Math.seededRandom = function(max, min) {
    max = max || 1;
    min = min || 0;

    Math.seed = (Math.seed * 9301 + 49297) % 233280;
    var rnd = Math.seed / 233280.0;

    return min + rnd * (max - min);
}

var c, r = 0,
    l = 100000,
    t,
    random = [],
    seededRandom = [];

for(var i=0; i<100; i++)
{
    random[i] = 0;
    seededRandom[i] = 0;
}

// Do some loops withouth benchmarking
// to have a "fair" comparison
/*for (c = 0; c < l; ++c) {
    r = 5+5;
}*/


// benchmark Math.random()
t = new Date().getTime();
s = '';


// benchmark Math.seededRandom()
t = new Date().getTime();
while(l--){
    r = Math.seededRandom();
    seededRandom[(r*100)|0] += 1;
}

var inc = 0;
for(c=0; c<seededRandom.length; c++) {
    //var inc=15;
    for(var i=0; i<seededRandom.length; i++)
    {
        if(i!==c) {
            if(seededRandom[c] == seededRandom[i]) {
            seededRandom[c] += inc;
            inc = inc + 10;
              //    console.log(seededRandom[c]);
            }
        }
    }
    inc = inc > 255 ? 0 : inc;
}

var a=[], b=[], d=[], inc=0, dec=255;
for(c=0; c<seededRandom.length; c++) {
    a[c] = (seededRandom[c] % 100) + inc;
    b[c] = dec - Math.floor(seededRandom[c]/100);
    if(b[c] < 0)
        b[c] = b[c]* - 1;
    if(a[c] > 255)
        a[c] -= 255;
    d[c] = Math.floor(b[c]/2);
    inc += 5;
    dec -= 5;
}


var app = angular.module("myAppp", []).controller('myCtrl',function($scope, $http) {
$scope.id = [];
for(var i=0; i<seededRandom.length; i++)
    $scope.id.push(i);

// Generate random number
$scope.Icon = [];$scope.Icon2 = [], $scope.Icon3 = [];

var ran = 0, inc = 5, dec = 255;
for(var i=0;i<seededRandom.length;i++)
{
    $scope.Icon.push(a[i]%100);
    $scope.Icon2.push(b[i]%100);
    $scope.Icon3.push(d[i]%100);
    console.log(a[i] + "|" + b[i] + "|" + d[i]);
}

});

它对我有用，我想它对你也会有帮助。

这个例子中最好的一点是，它将生成100个随机颜色，并且每个页面加载的颜色都是相同的。

另一个随机颜色生成器:

var randomColor;
randomColor = Math.random() * 0x1000000; // 0 < randomColor < 0x1000000 (randomColor is a float)
randomColor = Math.floor(randomColor); // 0 < randomColor <= 0xFFFFFF (randomColor is an integer)
randomColor = randomColor.toString(16); // hex representation randomColor
randomColor = ("000000" + randomColor).slice(-6); // leading zeros added
randomColor = "#" + randomColor; // # added

你可以试试这个。这是一个绝对随机和舒适的颜色生成器))

var Color = '#';
var myElement;
for (var i = 0; i < 6; i++) {
    function Random1(from, to) {
      return Math.floor((Math.random() * (70 - 65 + 1)) + 65);
}
    function Random2(from, to) {
      return Math.floor((Math.random() * (1 - 0 + 1)) + 0);
}
    function Random3(from, to) {
      return Math.floor((Math.random() * (9 - 0 + 1)) + 0);
}
if (Random2()) {
     myElement = Random3();
}
else {
     myElement = String.fromCharCode(Random1());
}
Color += myElement;
}
