[Orgmode] name of face for dates in org agenda?

[Brian van den Broek]

Hi all,

I've changed my overall emacs colour scheme and, as a result, the 
dates in the weekly agenda view are a bit hard to read (dark blue on 
black). I've looked through the interface that M-x org-customize 
brings up, but I don't seem able to find the governing face variable 
name. Little help?

Thanks and best,
