How to change font color in non-contact form fields.

[outrageous]

I cannot find any information to help me change the font in the credit card input fields including the card number, the date of expiration and the secret code fields.

 

The fields are backgrounded in black and the font is black, so you can't see what is input unless you highlight the text. But I don't have this problem on the contact forms or search forms as they are in white background with grey font.

 

Can someone help me figure out where in the css I need to change the font because I can't seem to find it anywhere. I've tried the global.css and cannot find where to edit this. Thank you.
