Excel 2010. VBA. UserForms.

I have a UserForm on which I have a ListBox control. The ListBox is populated with the contents of a range of cells on a worksheet. After the ListBox is populated, I want to go through the rows, check some values in the row, and then change the font color (to red) based on the values in the row. I know how to access the row and how to access the values in the columns in the rows. But I do not know how (if if it is possible) to change the font color of a row based on values therein. How can I do this?
