Blue Merle: The blue merle is a marbled or merled colour that is predominately blue-grey
and has white markings around the collar, chest, legs, feet and tip of the tail.
The blue merle also has tan markings similar to the tri-coloured Collie (around
the eyebrows and cheek area). The blue merle has the widest variety of colours -
you will find Blues with almost no merleing or almost all merleing. They can have
splotches of black or dark grey, or no splotches at all.
