I prefer dark colors whenever possible, preferably all one shade.
If it can't be all a dark color, I prefer dark dogs with either dark markings (like a black Rottie with dark brown points *swoon*) or minimal flashy white (like a pinto colored Akita *swoon*).
The exception to this is dogs that come in red merle. I love me some red merles.

I don't really know if I have a favourite anymore. I am more attracted to a certain type of dog or breeds vs. colours. But I like contrasty dogs and I prefer dark eyes. I like dark, rich colours. Tri colours and bi colours are nice though. Some brindles. Certain merle patterns. My favourite colours in my favourite breeds are...
Aussies: Black tri and dark red tri. Darker merbutifjulie either colour but preferably no bi eyes or blue eyes.
Tollers: Darker orange and not really particular about markings, but prefer a small snip of white on the face and four white paws. I kind of want a black nosed toller next whenever next toller happens.
Koolies: Dark solid red/red bi, dark red Merle, black tan/black bi/black tri.
Depends on the dog. I like rich, mostly solid colors. Reds, blacks. Tris. Certain merles, so long as there's white with tan/copper trim. Some brindles. Fawns with dark masks.
My favorite dog is a red sable.
Black and tan, in general, is my favorite on most dogs.
APBT: Black and tan, red or chocolate brindle, buckskin with a dark mask
Great Dane: Fawn with a dark mask, harlequin
Kelpie: Black and Tan
Standard Poodle: Black
ESS-tricolor. I always used to be a traditional Irish patterned black/white/tan girl. But those richly colored English marked liver/white/tan dogs get me now.
Tollers-I prefer a flesh colored nose with a rich red (not buff).
Aussies-dark merle with no tan.
English Shepherds-sable
Belgians Tervs/Mals/Laekens-full DARK black mask with black shading on the body.
