But all the earlier DEC video terminals (VT05, VT50/52/61t/62, VT20, VT71) were white.  The only exception I can think of is the GT40, probably because that one benefits from having fairly long persistence which was available in green phosphor but not in white.

The User Guide doesn't say and I don't have an IPB I can find. I do 
remember the VT100s in the computer room at Uni being green and the VT52 
clones (Dataram?) being white. But that's a while ago so maybe my 
wetware is wrong. If and when I can get to where I think my VT100 is I 
can look at powering it up. Powering it up may take much longer than 
getting to it though :-)

My VT220 is (or was, it's been a while ...) green phosphor and my VT420 
is amber ... I like both.
