JavaScript to generate random hex codes of color
What is hex code?
A hex code is a six-digit, three-byte hexadecimal number used to represent colors in HTML, CSS, SVG. The bytes represent the red, green and blue components of the color. One byte represents a number in the range 00 to FF (in hexadecimal notation), or 0 to 255 in decimal notation. This represents the least (0) to the most (255) intensity of each of the color components.
Functions to be used for generating hex codes:
Math.random() generates any no. between 0 and 1 including decimal.
Math.random() * 16 generates no. between 0 to 16 including decimal.
Math.floor() removes the decimal part.
<script> // storing all letter and digit combinations // for html color code var letters = "0123456789ABCDEF"; // html color code starts with # var color = '#'; // generating 6 times as HTML color code consist // of 6 letter or digits for (var i = 0; i < 6; i++) color += letters[(Math.floor(Math.random() * 16))]; document.write(color); </script> |
Output:
#E3B0DF
Note: Output will be different for everytime the code will get executed.
