I learned a lot in that exercise. Especially about how a single photo of a rose can mislead without a good description. And how a good description can turn bad when it is truncated. I was interested to discover a post-pernetiana hybrid perpetual which I had imagined would not exist. Finally, I found it interesting to discover the way bicolor traits can skip generations: foetida bicolor being the parent of Soleil d'Or which is not bicolor and SO being the parent of Juliet, which is.
A fun exercise, if a bit frustrating because of incomplete information at the start. But I guess that's the way most problems present themselves.
