excel 2010, checkbox macro to change text upon doubleclick of cell?

good day all. i am new here and new to excel vba. I have been doing alright but am stuck. I am in need of an example of macro code for this issue. I have multiple rows of data on my worksheet and 2 radio buttons on top in the 1st Row...data starts in the 5th row. I would like to be able to select one button and double click a cell to change that cell's text to red. if the 2nd button is selected i would like to be able to double click a cell and change its text to green. is this possible?

thanks
