When specifying web page colors, backgrounds, fonts and elements, you want to choose from the 216 colors that will look the same on both Windows and Mac operating systems. Web browsers can only work with the colors that are not reserved by each operating system. Since there are a total of 40 colors reserved by both operating systems, that leaves 216 colors for you to use. If you use one of the 40 colors, each system tries to approximate it with some combination of the 216 acceptable colors, which is called dithering. Unfortunately, each operating system does dithering a bit differently. The result on a web browser, such as Mozilla Firefox, or Internet Explorer is likely to not be what you intended.
By using the colors in the “browser-safe palette” table below, you’ll ensure that your colors will look the same on both operating systems. The table shows the hexadecimal intensity values you need to specify in the <BODY> tag for backgrounds and in the <FONT> and other tags containing color attributes. The first two hexadecimal (hex) digits are the red (R) value in the color; the second two are the green (G) value; and the third two are the blue (B) value. The six hexadecimal values create over 16 million possible colors and with a display adapter capable of providing those colors, all of them can be used.
As it happens, each RGB hex pair in the table below contains one of values: 00, 33, 66, 99, CC, or FF. Each block illustrates the effects of increasing the levels of each color. Each block of 36 colors, from top to bottom, contains a twenty percent increase in red. From left to right in each box, the amount of green is increased by twenty percent. From top to bottom in each box, each block shows an increase of blue by twenty percent. The hex value you would code is superimposed on the color it produces.
Most Web page creation or HTML editors include a facility that lets you easily view and select colors for your page. You may find this table handy, however, when your editor is not accessible. Photoshop and other art creation tools now tend to include some version of this table. I also included the 16 Basic Color Table for your information as well.
