Following is a sampling of HTML color codes used in HTML tags for setting background and font color. Colors are coded as red, green and blue intensities in hexadecimal notation (see hex chart).

As you can see, ColorTagGen is fast, and the handy Copy HTML button makes it a snap to get the hex-encoded values (e.g., #fccea7) onto the Clipboard.

Hex codes are especially useful for matching colors in an Illustrator document to those on a Web page, as both HTML and CSS use hexadecimal codes to specify colors.
