Part I: HTML > Color Names and Values

Chapter 8. Color Names and Values

With the popular browsers, you can prescribe the colors of various elements of your document via tag attributes or CSS style definitions.

You may specify the color value as a six-digit hexadecimal number that represents the red, green, and blue (RGB) components of the color. The first two digits correspond to the red component of the color, the next two to the green component, and the last two to the blue component. A value of 00 corresponds to the component being completely off; a value of FF (255) corresponds to the component being completely on. Thus, bright red is FF0000, bright green is 00FF00, and bright blue is 0000FF. Other primary colors are mixtures of two components, such as yellow (FFFF00), magenta (FF00FF), and cyan (00FFFF). White (FFFFFF) and black (000000) are also easy to figure out.
