At this moment it is NOT possible to change any colors inside Filr.
Especially if you need to create an account and your password is wrong... the colors are: WHITE on a YELLOW background.

I have created SR# 101223696951 to get this fixed.
Unfortunately it is not possible (yet). So that 's why this Idea.

@Micro Focus,
the guy/girl who originally created this Filr stuff.... was he/she color blind?
