The chart at left shows 125 samples from the more than 16 million colors that can be named using hexadecimal codes. These codes are used in HTML documents to specify the color of text and backgrounds displayed in web browsers. This chart gives you rough landmarks to find your way around the hexadecimal spectrum.

This is a rough guide only. The color created on your screen using a hexadecimal code may not match the identically coded color in this chart.

Each color code consists of six symbols. The first two are a hexadecimal number representing the intensity of red light in the color, in a range between 00 (= zero, no red) and FF (= 255, or 100% red). The second two symbols show likewise the intensity of green light in the color, and the last two symbols represent the blue light.

The codes on the left edge of the chart show hexadecimal values for the red and blue components of the color. The symbol "xx" for the green component means that you are to choose that number from the column in which your desired color lies.

For example, the code for the color in row 3F xx 7F and column BF is 3FBF7F, a medium grayish green.

NOTE: When you enter the code into an HTML document, do not put spaces between the pairs of symbols. The spaces shown on this chart are for clarity only.
