Thank you! I was thinking of Tivoli outside of Rome.

As for the imprimatura it can be used with some success in digital painting. it gives a tone to the layers involved and that "collects" the different parts of the image. It is on the other hand very different and also a bit more primitive than when applied on a real painting - there is first of all a very big difference between additive and subtractive colours (the way they blend), more important is that there is no physicality in digital painting so the sense of real layers is only simulated, and can easily disappear when things get complicated. There is after all only one pixel.
