Color Tables
Of interest to UT Web authors/designers: the Pantone Internet Color System Guide (ISBN 1-881509-94-X) shows #cc6600 as closest to "UT burnt orange." It may not appear so on your screen; the wide disparity in color calibration among computer monitors makes it difficult to predict how accurately color will be rendered across the Web. It is best simply to specify the appropriate color and not worry too much how the result will appear on a given monitor (including your own!). Named ColorsThese 16 colors can be specified by name; they were chosen for the HTML 3.2 recommendation because they are the standard colors supported in the Windows VGA palette.
RGB Hexadecimal Coded ColorsColors may also be specified by six-character codes representing their relative red/green/blue (RGB) values, where the possible values for each color component are 00, 33, 66, 99, cc, and ff. The six charts below display the 216 possible colors in the browser palette with their hexadecimal RGB codes (a seventh chart displays the gray scale). In each chart the blue value is constant, the vertical axis represents increasing red values, and the horizontal axis represents increasing green values. The six charts can be visualized as a cube composed of 216 cubelets; the total cube has six layers of thirty-six cubelets; each cubelet is a unique color. Using this metaphor, black (#000000) in the lower left of the first chart is one corner of the cube and white (#ffffff) in the upper right of the last chart is the opposite corner of the cube; the cubelets running through the body of the cube in a line from black to white comprise the gray scale.
HTML Attributes to Specify ColorIf one of the following <BODY> attributes is used, they all should be specified in order to avoid color conflicts; for example, you may assign a backgound color and a visitor may have his/her browser set to display text in the same color, making your page unreadable. All these attributes should be specified in a single <BODY> tag.
