How to change color of Alert Message Boxes?

I'm trying to change the font color of the alert box messages (i.e.  "Your Profile Has Been Updated", "Your Current Membership Does Not Allow You. . .").  Right now they are light gray (hard to read).

Thank You in advance.

I found it if anyone needs to change the font color for message alerts:

yourdolphinsite/templates/base/css/common.c

It's located Line 275 .MsgBox .msgbox_text

Thanks for this :)
Mine was at line 140 for some reason..lol but none the less all sorted !

Cheers
