In creating your website it can be very useful to know the hexadecimal values of RGB colors and vice versa. For instance if you need to match a graphics color to your background value all you’d need to do is find out the RGB value of the graphic in your graphics program and convert it to HEX.
On the other hand if you already have a web page designed and you’d like to make a header graphic for your site you could take the HEX background color and convert it to RGB for use in your graphics program.
Sound like fun? That’s what I thought when I stumbled upon this nifty little ‘online HEX to RGB to hex Color converter‘ from 321Webmaster.com.
