I personally love Maine coons and for cat fur color my favorite is black as my most loyal friend for 15 years of my life was a black cat named Killer/Kitten-nyah.
My first two cats as an adult, that I *really* bonded with... were both orange tabby's. They were one after another, clones of each other. WhIle I loved all my cats, the next time I had a long relationship was with a tortiseshell, you know, the dark calico. so orange tabby's and dark calico's are the highest on the list.
Apparently Greece has its own breed, the Aegean Cat, and I had no idea my whole life until something like a couple of weeks ago. So I'd say that, gotta represent But also its a very pretty cat breed. As for favourite color... I'd say calico. But local cats are aslo very pretty, with their (usually) grey backs and white bellies. Wish I was on my phone to add some of the strays in my neighberhood, but alas. Use your imagination
