Portal 7.3 Logoff Container Font and Color

Hi All,

I am working on Portal theme customization, I made Masthead background color Grey. So I need to make the logoff Container, Help, View Full Screen font color White.

I changed the Font Color of Hyperlink Container = #FFFFFF, but still its not getting changed.

And also tried Simple Elements -> Links -> Standard Hyperlink and Function Link changing to White, its not getting changed.

If anyone faced the same issue and solved, please help.

Regards
