Dropdown Menu Boxes

Just a quick question, is there anyway to predefine a dropdown menu via a url

is if you have a dropdown box with the following options in it

red
green
blue
black
yellow.

is it possible to specify one of these automatically via a url

/index.php?route=product/product&path=64_72&product_id=59&option=red

thanks

/index.php?route=product/product&path=64_72&product_id=59&option18&value=263

this would select the dropdown box for my colors and then the vlaue 263 would be red.,

anyone ?
