Yes, this stood out to me too.
I went with black, but if there is proof that it is indeed red I'm happy to know.

Bob,
I don't actually have the book but a friend has sent me the relative info in the form of scans. My understanding is that red is based on the following:
1. The stripe appears darker than the chrome yellow but lighter than the black crosses.
2. Apparently Klein used red stripes on an earlier Albatros DV while with Jasta 4
3. He served in a regiment that had red hat bands as their color.
All Very circumstantial but I like the red so will probably go that way. Remember that Greg van Wyngarden in his usual style said the stripe was "Probably" black
