I don't think Porsche really makes those kinds of figures public domain.
On color: I've never seen statistics anywhere in 25 years of Porsche interest/ownership. No doubt the marketing department has them and treats as proprietary data. Would be interesting to see how color rankings have changed over the years by model and country. I could envision a Christophorous article along those lines...
On manuals: same situation insofar as raw detail data. Porsche have been quoted somewhere (IIRC) with an 80% PDK figure worldwide, but I don't know if that is 718 or combined mid-and-rear-engine cars. I think we have a relatively high proportion of manuals here on the forum, which makes sense given the concentrations of custom-factory-orders and sport driving enthusiasts here.
