Browser Safe Color Palette

Below is a color chart made up of the 216 browser safe colors. Netscape, Internet Explorer, and Mosaic each use a palette consisting of the same 256 colors. However, 40 of those colors are slightly different on PCs and Macintosh computers. The 216 colors below are those that are the same on both PCs and Macintosh.

The RGB (Red, Green, Blue) formulas that make up each color are mathematical calculations, not artistic choices. By examining the hexadecimal code representing each color you can see the math progression. Hexadecimal numbering (base 16) is represented as numbers 0 through 9 and letters A through F. The codes noted on the chart below consist of a two digit figure for each color. Thus, the code for red is FF0000. The code for green is00FF00. The code for blue is 0000FF.
