JavaScript Program to Generate Random Hex Codes of Color

Last Updated : 31 Oct, 2023

What is hex code?

A hex code is a six-digit, three-byte hexadecimal number used to represent colors in HTML, CSS, and SVG. The bytes represent the red, green, and blue components of the color. The hex codes are an integral part of HTML for web design and are a key way of representing colors digitally.

Methods to be used for generating hex codes:

Math.random() method generates any number between 0 and 1 including decimal.
Math.random() * 16 generates no between 0 to 16 including decimal.
Math.floor() method removes the decimal part.

Example: In this example, we will generate a random hex color.

javascript

// Storing all letter and digit combinations 
// for html color code 
let letters = "0123456789ABCDEF"; 
  
// HTML color code starts with # 
let color = '#'; 
  
// Generating 6 times as HTML color code  
// consist of 6 letter or digits 
for (let i = 0; i < 6; i++) 
    color += letters[(Math.floor(Math.random() * 16))]; 
  
console.log(color);

Output

#9B0945

Note: Output can be different every time the code will get executed.
