When you want to change the color of text and backgrounds in HTML you specify the color attribute value in what is called RGB hexadecimal notation. An RGB value represents the brightness (amount) of Red, Green, and Blue in a color. When choosing colors for your Web page it is best to choose colors from the 216-Color-Safe-Pallette, or the HTML Standard Color Map, which refer to the colors that the "system pallette" of different computer systems have in common. The standard map colors are combinations of red, green, and blue at six different brightness levels: 00, 33, 66, 99, CC, FF. An 00 value means the color is OFF, and an FF value means the color is at it's brightest.
