Mine are mostly the same. I like merles (but am kind of picky about them), and I like bi and tri colours. Sable and brindle have grown on me, though. I never used to care for them that much for some reason but now I think they're very pretty. And I used to prefer minimally marked Tollers with little or no white especially on the face, but now I prefer facial markings. And four white feet.
And I still have a huge preference for dogs in shades of red or brown for the most part, and probably always will. Especially if they have pimgent/noses that match their coat (liver Dals, red Dobes, liver Flat Coats, Tollers, Vizslas, red bi, tri or merle Aussies/Koolies/Border Collies, etc.).
Mostly the only colour scheme or what have you that doesn't grab and hold my attention is a solid coloured dog usually. I tend to prefer flashier dogs/something with markings. But there are some breeds I like that are solid in colour (Flat-Coats, Belgian Groenendaels, Chessies).
That said, when looking for a dog, colour is not my top priority. I would try to seek out a breeding/litter that would give me my preference in colour, but if that doesn't happen, then I don't really care just as long as the temperament is a good match.
