You will find herein the most frequent Border Collie colours, which coat may be of different colors, from black and white, to red merle, blue merle, brown or chocolate, or combinations and variations of these. Anyway, and even if, from an aesthetic point of view, each person may be kind of any of these colours -from the most frequent to the rarest- it is true that is just another element to be taken into account, together with others not less important than the color is, such us the instinct and skills at work, essentials of the breed, together with those of the standard.

Again, as it couldn't be otherwise, genetics plays the main rol. The concurrence of genes -dominant and / or recessive - will bring about our dog has a coat coulour or another. The coat color, as well as mucous of our dog is determined by melanin, a pigment that may be eumelanin and phaeomelanin.

Depending on how they affect the coat colour, genes may classified as affecting the basic colors, and genes modifying these. Variety of colours is permitted by the standard, even if white should never predominate.

 

BLACK & WHITE

 

 

Black and white combination is, with no doubt, the most frequent. The nose, deep black, specially brings out in these dogs. When dominant B gene (bringing out black color) is present, and even if the specimens may be homozygous (BB) or heterozygous(Bb), the Border Collie will always be black and white.

BLUE OR GREY

 

 

The called Blue or Grey Border Collie is due to the presence of a dilute gene, so the deepness of black color is blended, to bluish, slate or dark grey. As well as it happens with other coat colors, the differences are easily seen on puppies (better than on adults, whose coats gets darker).

BLUE MERLE

 

 

The Merle gene is dominant, so it is enough with just one M gene to get this patchy pigmentation. M gene acts on eumelanin, and dilutes, strongly or not, on the basic color -brown or black- giving blue merles or red merle-.

AUSTRALIAN RED (ee Red)

 

 

The Extension gene ( ee gene) "masks" in some way the color that, genetically, the dog has. Such pigmentation may be seen by means of evidences such us the nose or the lips. Thus, should these parts of our friend be black, the B.C. would be, from a genetic point of view, black. And when the nose is brown, this would be the basic color. When grey, a blue color will be on the basis -diluted black- and lilac, when the nose is cream-colored or pinkish.

Tricolor gene is recessive, so this coat will only appear when two tricolor genes are present. Dominant basic black bring out a black tricolor B.C. Unless unexpect exceptions, matting two tricolor specimens will produce only tricolor puppies.

TRICOLOR MERLE

 

 

Merle elements over a tricolor basis. Merle -in contrast to dilute gene, blending the pigmentation on a homogeneus way- the Merle brings out an 'irregular' or patchy pigmentation, strongly or rather subdued, depending on each case.

"CHOCOLATE" (BROWN/RED)

 

 

Chocolate specimens (also called brown or liver) have a brown nose and eyes, that may be also greenish. Gene "b" being recessive -against dominant B, black- causes that brown specimens are, necessarily, "bb". Over brown pigmentation, other genes may act (as it occurred with black color) (merle, dilute...).

TRICOLOR CHOCOLATE  

 

 

Similar to black tricolor negro, but with a brown basis instead of black. Tricolor gene is recessive, so pigmentation of tricolor chocolate will only appear when two tricolor genes will be present.

RED MERLE

 

 

The term 'red' is due to the reference that, in some areas such in the USA is made to brown border collies (nothing to do, thus, withl ee red or golden red). From a genetic point of view, "red merle", chocolate merle are quite similar to the blue merle, but the brown color is on the basis instead of the black color. Blue Merles, however, show up more often, Red Merles being by far much more scarce. A 'bb' specimen is needed (brown or chocolate color) plus a M gene.

LILAC (DILUTED BROWN)

 

 

Lilac specimens, as it happens with grey or blue BC, have a dilute gene but in this case over a brown basis. Again, combination with white is frequent, on legs, mouth and head. Nose is often cream-colored, evidencing the chocolate basic pigmentation.

SABLE & WHITE

 

Coat of sables (sand) evidences a blend of eumelanin and phaeomelanin, so the hair is lighter at the basis and gets darker at the end. This brings out a copper-colored coat, blended, in combination with white. As said with other speciments, the nose and lips colors may reveal the basic pigmentation of the dog.

SEAL  MERLE  TRICOLOR

 

 

By far, one of the rarest colors of this breed. It may occur by matting a tricolor and a merle. The patchy features of merle can be seen easily when the dog is still a puppy, becoming homogeneous as it growths. The dog is 'sable' gene carrier on the A (agouti) gene but not of the double recessive over the black, so it causes that the usual features of sable are not shown as usually.
