For some reason colors in HTML are specified using hexadecimal numbers.
Hexadecimal numbers are numbers based on the value of 16 rather than the classical numbers based on the value of 10.
When you count to 15 using hexadecimal numbers it goes like this: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
As you see the numbers from 10 to 15 have been replaced with letters.
A typical hexadecimal color value would be A53C8D.
In this section you will learn how to understand hexadecimal color codes.
You will also learn to convert between hexadecimal and RGB color codes. (RGB codes are used by most graphics programs to identify colors.)
Finally you will learn about an error in the color interpretation by Netscape browsers, causing only 216 colors to look the same on all browsers.
First we will proceed to learn about the difference between hexadecimal numbers and traditional numbers...
