I'm used to more "modern" lenses from nikkor and the coloration given by the coating is very evident... so, I don't know about this lens, but I cannot recognize any color on the taking lens.

I also use nikons. My Rollei is the "T" model with a Tessar lens, in terms of coating probably similar to your Xenar.
I find it quite a bit "cooler" (i.e. bluer) than my Nikon lenses when using transparancy film. An 81B is usually needed to add warmth to colour tranny film shot in the Rollei.
