Yes, default is purple.  That was a side question - not the main one.

I think problem you mention was an old one in Firefox.  For years, 
Mozilla disabled visited links from changing color due to a bug.
I think that was fixed, but doesn't mean that TBB design wants them to 
change color (for highest anonymity / least fingerprinting).
