Text Box Font Color

Hello,

I have a department that wants a survey that has a black background with white text.

This is not a problem until I add a radio button question and add the option for "other".

In the style I have defined, the "answer" font controls the font color for the text within the text box for the other option. Which is "white" on "white" and the user can't see the text that is typed.

How can I control the text color within the text box only and leave the remainder of the page's font color white?

Thanks!
