You can create an array containing a limited number of different color names and then randomly pick a color from that array. HTML color names like red, blue, orange, and orangered are intuitive and easy to remember than color codes. Script.js:18 hsl(324, 8%, 43%) Get a random color name from an array of color names You can also use a loop or an array to concatenate the characters into a string.Įxample: const getRandomHexColor = () => %)` The solution to creating a random hex color code is to use the Math.random() function to generate random numbers between 0 and 15 and then convert them to hexadecimal using the toString(16) method. Each digit can be from 0 to F (or 15 in decimal). = randomRgbColor() Generating random hex color codesĪ hex color code is a six-digit code that starts with a # and represents the amount of red, green, and blue in a color. You can set a random background color for a div element like so: const myDiv = document.querySelector("#my-div") Output (note that the output is not consistent due to the randomness): rgb(76,125,16) Let b = Math.floor(Math.random() * 256) // Random between 0-255 Let g = Math.floor(Math.random() * 256) // Random between 0-255 Let r = Math.floor(Math.random() * 256) // Random between 0-255 And then, you can concatenate them into a string with commas and parentheses. To generate a random RGB color in JavaScript, you need to create three random integers between 0 and 255 using the Math.random() function.
