Using Hex Codes to Design Your Website

Understanding a little bit about Hex Codes comes in handy if you are designing your own website, updating a free web template to better suit your needs or if you want your business cards and promotional items to exactly match your website.

What exactly is a hex code? Well, when you went to school and learned math, the system you learned was the decimal system or base 10. In base 10 we use the numbers 0-1-2-3-4-5-6-7-8-9........look familiar? 

Computers on the other hand use a different system called the hexidecimal system or base 16. Because we don't have symbols to represent 10-11-12 etc we use letters to represent those numbers. 0-1-2-3-4-5-6-7-8-9-A-B-C-D-E-F

So what does that have to do with colors? Well, I'll tell ya. Computers see colors in RGB (Red, Green, Blue), each of those can have a value from 0 to 255, with 0 being the absence of color, 255 being full color. 

Example: Red = 255-0-0 
                   Green = 0-255-0
                   Blue = 0-0-255

Here is a chart showing the hexidecimal..................
