Try the Web-Safe Color Palette
Note: The Palette Chooser requires frames and JavaScript to interactively pick colors. Then you can see your color picks next to
each other with combinations of text and background colors. On the left is the “color menu” used by the color lab. If your browser supported
frames and JavaScript, you'd be able to hover over the colors in this menu and see the 6-digit RGB (hexadecimal equivalent) values on the status line.
