Css selector of radio and other widgets

Hi i have a page with more than ten widgets elements, and i need to change all them to one color.

I could find the information about buttons, but i do not see anything about radio button selector or selectbox.

The main thing that i would like to know is where cand i find the css property of a radio.

I need to change all the colors to green when are selected.

Is not usefull for me to reach em by its particular class. It should be a universal one to edit one or all, and also i would like to know all the properties available to customize the widgets.

Any idea?

Thanks in advance.
