Hi I am working on a small furniture website and want to place a link on a given page, from clicking on the link another browser window will open which will be a set size and in it I want to display thumbs of the colors for the specific product.
Can anyone point me to a how to?

If you want web colors, try searching "color picker" There ar JS tools out there to do this.

If you only need to open a popu window, then use DMX's "open browser window" behavior or the Advanced Open Browser Window extension found here
