And a combo might look great on your true-colour monitor, but be considerably less appetizing on a 256 monitor, as your browser tries to dither them. There are one or two Javascript ones that would do so, but they must be run in a browser. The palette displays them.
Color changes produce code changes in the body tag text.
Clicking a button sends the HTML code for the colour combo to the clipboard. From there, you can paste the code into your HTML file. Just recently I finally learned enough VB5 to augment the picker with selection of a background image file and tiling it between the sample text. Very few freeware utilities provide both a browser-safe palette and the ability to test your text colours against a tiled background. It worked fine on my machine at work, but refuses to store the tiling image name on my machine at home.
