Different possible methods for generating a colour randomly in JS

In this post, I will be summarising several possible methods for generating a colour randomly in JavaScript.
So, Save this article !
As you might be aware of how colours are represented, i.e, Hexadecimal code with a '#' prefix --> #RRGGBB
The code for Black --> #000000
and for white --> #ffffff
Hence higher the values, more the colour will be lighter and vice-versa.
Here's the different methods:

• Method 1 In this approach, simply take a string of all possible hexadecimal characters, then choose from it randomly and concatenate them to form a 6 digit hex code.

const s = "0123456789ABCDEF";function getRandomColor() {    let col = "#";    let temp =0;    for(let i=0;i<6;++i)    {       temp = Math.floor( Math.random() * s.length ); // generates number between 0-15       col = col + s[temp];    }return col;}

for generating lighter/Darker colours only, we can use sLight or sDark respectively.

const sLight="789ABCDEF";const sDark="01234567";

• Method 2Similar to the first one but here instead of predefined string, we can use toString(16) to convert to HexaDecimal.

function getRandomColor(){    let color = "#";    for(let i=0;i<6;++i)        color += (Math.floor( Math.random() * 16 ).toString(16) );    return color;}

• Method 3We can use the following ES6 approach :

const getRandomHex = from => to => () =>    Math.floor(Math.random() * (to - from) + from).toString(16);const getRangedRandomColor = from => to => () =>    `#${[...Array(6)].map(getRandomHex(from)(to)).join("")}`;const getRandomColor = getRangedRandomColor(0x0)(0xf);const getRandomColorLight = getRangedRandomColor(0x7)(0xf);const getRandomColorDark = getRangedRandomColor(0x0)(0x7);

Thanks to @lukeshiru for this one, and you can find the detailed explaination for this in the comments section of my previous article here

• Method 4

function getRandomColor() {    function c() {      var hex = Math.floor(Math.random()*256).toString(16);      return ("0"+String(hex)).substr(-2); // pad with zero    }    return "#"+c()+c()+c();}

substr(-2) means take last two characters of the string.

• Method 5This one is a great one liner for the same I found on StackOverflow.

function getRandomColor() {    return '#'+(Math.random().toString(16)+'00000').slice(2,8);}

Well these were some of my picks, if you want to dive in more, you can have a look at this thread on StackOverFlow.
