Why div print colors instead of numbers?

I was wondering, why would the div print color as a hexadecimal, instead of just number. Cool trick on how to make div colorful, but i am lost.

Hi Ammar,

You can specify colors in multiple ways. Hex does seem to be the most common. They can be specified by name: http://jdstiles.com/colorchart.html

Or by Hex, RGB, and HSB http://www.rapidtables.com/web/color/RGB_Color.htm

Wikipedia has a good article on web colors: https://en.wikipedia.org/wiki/Web_colors

Not a Hex value, but rather an RBG value. the random numbers are being applied as RGB values and then being inputted as an RGB background color for each div in the loop. It's one of many really cool ways you can use Math.random() to manipulate number values in JS.
