TOPIC: How to change font colour in marker Popups ?

My main page is black and font is white/light grey.
When i open a hotspot in map there is a white background and a light grey font colour - so there is no contrast between background an font.
Can not find a definition in CSS file to change font colour for the markers..where is it ?
Can you help ?

Version 4, no longer has a Popup, so we'll have one less problem to worry about
Cheers,
Daniel

Can we still turn on the popups? We don't like the way the current version hides the map from view.
Or, can we download the latest version that does have the popups? Got a link?
Thanks!
