This is a point of controversy among people interested in WW I
aircraft markings. Most references for this particular aircraft indicate
that it was painted red and white. Heinz Nowarra, who provided most of the
photos for Squadron's "Fokker Dr-I in Action" , published a color profile
in that book showing Raben's triplane to be blue and white. This is the
only place I know of where a blue and white macine is illustrated. I have
seen a piece of fabric purported to have come from Raben's triplane. It is
pretty clear looking at the fabric that a coat of red paint was applied
over a coat of medium blue.

I believe that Raben operated this machine after April 1918, in which
case straight sided Balkenkreuze would be the national markings. You would
have to see how late into 1918 this machine was operated to know what style
of cross might be in use.
