In Bruno Schmäling & Winfried Bock's Jasta 30 book, it's shown with Silbergrau on the wing undersides. The stabilizer is wine red on both surfaces; Jasta practice was to have the diamonds on both upper and lower surfaces. In the top view, there is no diamond on the upper wing, but I couldn't resist adding it on my model (still unfinished). There's also a profile of von der Marwitz's D.IIIa in Feb/March with the wings still Silbergrau overall, and still having Eiserne Kreuze. All other colors are as in the later version. There is no top view of this scheme. On both profiles, the red on the tail shows a straight vertical line, including the rudder balance, which seems to have been common in Jasta 30. So far, I had left my rudder white overall, but have debated adding the red segment at the top. Since there is still only the one photo known, which does not show the tail. it could be either way. As for struts, I went with red for cabane and interplane struts. However, in the photo, I think the forward undercarriage strut looks lighter, went with the blue on those. That also matches his colors on his other Wine Red machines, as shown in the book profiles (Alb D.V, Pfalz D.XII, Fokker D.VII). Those others had blue on the wing struts, but on the Pfalz they look as dark as the wings in the photo. Since they are in shadow, it would be possible that they're blue, also.
I'll be interested in your version of Wine Red. I used a Tamiya spray color called Dull Red, TS-33, and I'm very pleased with it.
What ever colors you decide on, it's sure to be another masterpiece! Looking forward to following this build log.
