how can I designate a checked radio button in a URL link?

I am trying to figure out how to automatically have a specific radio button be "checked" once a specific URL link is clicked. For example..
If my radio button options are:
*All colors
*Blue
*Red
*Green
Pretend that the "All colors" radio button is always the default selection and is always populated with the check. I want to be able to create a link that would override the "All colors" selection and default to have the "Blue" radio button checked. But only when this specific link is clicked. All other times, the "All Colors" would remain checked. Any ideas of what the formula in the URL link would be to make this happen? Thanks for your help!
