COLOURS OF THE RAINBOW
These colour definitions
are as accurate as
possible
according to the information
currently available. As we learn more about the complex genetics that affect coat colour
inheritance and colour development
in the Havanese, some definitions may be added, removed, expanded or changed. Havanese
colours are intriguing.
It will be many years before we know all
there is to know about it, if we ever do.
These are mixed
colour combinations which
contain a blend
of both light and
dark coat
pigment in
varying
proportions. These are all patterns NOT colours.
Note that the
light colours in
each of these
combinations are
cream, gold ,
red, and not
white.
Patterned coats
broken with
white will be
discussed below. All these light/dark blended coats are possible in either black or
brown pigment. |
BRINDLE - Much confusion surrounds
brindle markings.
Brindle combinations give dark bands, more or less regular tiger striped on a lighter
background any shade
from cream, champagne, tan, gold or red. ( ie. Similar to brindle coats of the Boxer or Dane).
Tiger stripes are
apparent at birth and may run all over the body from head to tail tip in splotches, streaks or
stripes of black
or brown and to a lesser extent on the belly and underbody. Stripes may be bold and distinct or
faint and subtle. Brindle dogs often have a dark
mask on the face and at birth,
may have black ears, paws and tail as well as a dark dorsal stripe. New born
Brindle puppies will have a definite striped or mottled appearance. |
SABLE - Sable coats are distinguished by
darker
tipping on a lighter coloured underfur or a dark overlay on a
lighter base coat. The amount of tipping may be very heavy or very light. The underfur can be
red, gold, or cream . Tipping may be black, charcoal, silver or darker shades of brown. If the
tipping
is cut off,
generally it will not return as deeply. Areas will the most concentration of black hairs are usually
the ears, tail and along the lower spine. Some Sable dogs
lighten dramatically as they mature almost to pale Ivory or Off-white
leaving just subtle
shadings and highlights of colour. A true Sable will always retain some dark tipping (even if
just a few hairs) on the ears and/or
tail or have some individual dark hairs long the spine. |
AGOUTI - or WILD - Some Havanese
are said to have agouti hair,
where each individual
hair is banded in three to five or more rings of alternating dark/light colour like a rabbit
or wolf. In dogs, Agouti coats are found on the Keeshond, Norweigan Elkhound, Siberian
Huskies and other Spitz breeds. The ring changes are abrupt
dark to light and not at all like the shaded bandings you may find in Sables and brindles. See
below. The
coat will be banded on the neck, shoulders, back and rump and be lighter coloured on the chest
belly and inner legs. Controversy exists
whether Agouti is a
separate pattern of its own or a variation of Brindle or Sable. In other breeds, Agouti is
genetically
different from both. The same is likely
true of Havanese. Not only an individual colour or marking, the term "agouti"
is also the broader name of a gene which encompasses many patterns. See
the inheritance page for more information. |
SADDLE - Some
Havanese carry
a
SADDLE gene. This is usually a puppy born
black with tan/silver points, where the coat colour starts fading from the front towards the
back, stopping around the shoulder area, leaving the front, face, head and neck lighter and
the shoulders,
back and rear darker. Similar in appearance to the pattern on a Yorkshire or Silky Terrier.
|
BLACK AND TAN - is a very
specific layout of dark and
light coat.
Predominantly dark coat overlaid with a
lighter colour point pattern. Though the most common background coat colour is black, it may
also be Sable, Silver or Chocolate. Colour points are laid out in the following pattern;
lighter markings
appear on the muzzle, eyebrows, ears, cheeks, legs, chest and vent (similar to
the markings
on a Doberman or Rottweiler). Colour points may be solid or brindled and any shade of tan or
gold
(Tan Point) or
silver (Silver Point). Points often lighten to silvered pearl or creamy white as the dog
matures in part due to the Chinchilla gene. |

Figure1 - Agouti "wild" Banding (dark light)
Figure 2 - Eumelanin Banding (shades of dark)
Figure 3 - Phaeomelanin banding (Shades of light)
BANDING - There is a lot of
confusion in
regards to banding. Part of the confusion is because the term Agouti is used both to describe a
series
of genes, the "A" genes, and also because it is sometimes used as a colour name. Just because a
coat is
banded does not necessarily make it Agouti (Wild). Agouti (as a colour) is banding of dark coat
(eumelanin) and light coat (phaomelanin). Figure 1 on the left
above. This photo is a close up of wild rabbit fur. The coat changes are quite abrupt as it
changes from
dark to light in the same hair shaft. Though the photo appears circular, the wild patterning is not
a
circular pattern. This photo was taken when blowing on the coat to show the band layers right
down to
the skin. Other coats can be banded as well. Both Sables and brindles often have bandings in the
light
areas of their coats. These will be shaded bandings, with the bands growing in many shaded of
the same colour, so there can be bands of gold, champagne, caramel, cream etc. Those are all
clear shadings (phaeomelanin) - see figure 3 above on the right. Similarly dark coats can also
be banded , especially in dark and light silvers. In these, the dark coat is banded in shades of
dark coat
only(eumelanin). So the banding can be black, charcoal,, silver, etc... all shades of dark coat
colours -
see figure 2 above in the centre. The banded shadings may be caused by input of the wild gene
though
this is not certain. Agouti (wild) is also not the same as sable. Sable coats only have the dark at
the
tips or ends of the coat or as individual dark hairs. The dark coat is not banded into the rest of
the
coat.
|
These are the dark coat colours based on BROWN. Chocolate dogs are produced
when the coat, nose and eye pigment are brown instead
of black. Chocolate is not a dilution of black. A chocolate dog does not make any black at all. It
makes
brown instead. Eyes may be a light brown, hazel or amber colour.
Chocolate may be
the dark colour in all the same variations, markings and patterns as black so there may be
Chocolate Sables, Chocolate Brindles, Chocolate and Tan etc.
Nose and eye colour
combination is the most
reliable indicator of
whether a dog is
actually chocolate or if it just has poor pigmentation. If your dogs eyes are black with a lighter
brownish nose
then what you have is poor pigmentation and not a
chocolate.
|
CHOCOLATE - Puppies are born
chocolate.
True
chocolate dogs will have self-coloured brown or liver
pigment. They also have lighter brown, amber or golden eyes. Chocolate coats may vary from
Milk Chocolate to darker bittersweet
Chocolate colour. Any dog who makes [bb] brown pigment will have liver or brown nose, pads,
eye rims, lips and clear or brown nails. There is no black on the dog what so ever, in either coat
pigment or leather pigment.
|
CHOCOLATE SILVER (dark) -
Puppies
are born
chocolate and lighten as they mature. One copy of the
silvering gene affecting Chocolate may give rise to a medium to dark Mocha type colour.
Silvering
generally starts in adolescence and may progress over 2 to 3 years or longer. Pigment is
liver/brown.
|
CHOCOLATE SILVER (light) - Puppies are
born
chocolate. Silvering starts very early and is generally complete at about 12-15 months of age.
Two
copies
of
the silvering gene lighten the dog as it matures to a chocolate silver
colour similar to a light coffee. Pigment is liver/brown. Chocolate with one or two copies of the
silvering
genes, Chocolate
Silvers (light to dark) will
generally be
registered as Chocolate (birth colour). |
| So what about FAWN ? Where does it fit in? -
Fawn is a tricky one. Some
consider a fawn
puppy to be a medium yellow colour ranging from tan and buff to
light brown shades (like a Fawn Pug). Others call a light cream sable with beige/ brown tipping
Fawn,
and yet
others reserve the designation for the Dilute chocolate (cafe-au-lait) puppy.
|
| These are
considered Dilute
colours and develop similar to the colour found in Weimaraner. These dilutions of black and
brown are relatively
uncommon in Havanese but do exist. See the colour inheritance pages for information on how
these
dilutions occur. In other breeds, these dilute colours are called Cafe-au-Lait, Lilac, Mouse, Pearl,
Grey
and Isabella.
|
DILUTE CHOCOLATE -
Café-Au-Lait
colour. The dilute chocolate puppy is born pale watered coffee
colour or silvery bronze. He has light brown or amber eyes and self coloured light rosy brown
pigment.
|
DILUTE BLACK (BLUE) - Dilute black
puppies are born
a silvery blue colour. Eyes are light brown, amber or in some cases grey/blue; they have
self-coloured blue/gray pigment.
|
HAVANESE MARKINGS
Different
genes affect the
markings and
patterns.
One of these is the "Spotting" gene which causes a broken appearance to the
coat. Think of white as a mask hiding the colour beneath. Wherever there
is a "hole" in the mask, the colour shows through.
TRI-COLOUR - There are
variations - These three
colour coats are a result of the White
spotting gene acting on a Black and Tan Coat.
Some registries do not have
TRI-colour designations and use other terminology to describe these colours.
|
EXTREME PIEBALD - Two
colour
coat. Lightly marked dogs with less than 10% colour are
called extreme Parti or extreme Piebald. An example might be a white dog with one or both
ears partly coloured and no coloured patches on the body. |
PARTI-COLOUR or PIEBALD - Two
colour
coat. Coat
is predominantly white (over 50%)
broken with irregular patches or spots of a second colour. These patches may be any other
colour. Particolour is also used as a general term to indicate any dog with any extent of white
markings. |
IRISH PIED - Two
colour
coat with over 50% coloured. Coat
pattern is laid out as follows; The underbelly and lower legs and tail tip are
white. There is also white on the chest, and a full or partial
white collar around the neck. There may be a
white blaze on the face. The colouring on the back appears as a large
cape covering the shoulders, back and sides. |
WHITE MARKINGS - Two colour coat -
Predominantly
coloured coat with
small patches of white trim found on the chin, chest and
feet. Some also have a small white star or blaze on the face or
forehead. |
TRI COLOUR - CLASSIC - A classic TRI is
basically a
Black and Tan dog with the addition
of white in the parti or pied marking pattern. Some registries use the
terms Black and Tan with white markings rather than Tricolour. Three colour variations also
occur with
silver points rather than tan, or other dark colours rather than black.
|
TRI COLOUR - HOUND MARKED the
markings are
similar to a Beagle or other hound
breeds. Typically the markings are
Black and Tan or Sable appearing on the head, legs and saddle. Some call this a Bi-Coloured
Parti.
|
MODYFYING GENES AND VARIANTS
| These are
genes that
interact
with other
genes and modify their expression. Modifiers in large part are responsible for the widespread
variations. |
GRAYING - Many Havanese carry
the GRAYING gene to some degree (not the same as the slivering
gene). This gene is responsible for colours that
progressively soften as the dog matures, like prematurely greying hair in humans. In the
Havanese, this premature greying may start soon after birth or begin later in life. Some colour
changes
can be quite
dramatic. |
TICKING - Many Havanese carry the
TICKING gene. A
parti coloured dog with this gene will
have flecks of colour throughout the white coat, giving it a salt and pepper appearance. Dogs
without this gene will have a white that stays crisp and pure. In the canine world, an often used
term for this is "Belton" |
The CHINCHILLA gene appears to act
like a
filter
limiting production of red. This is the gene that allows variations or Red, Gold, Champagne etc.
Very
noticeable on Tan Point dogs.
This causes some confusion as many Tan Point dogs (as adults) have no visible tan on
them at all! Depending on the intensity of the gene, the points can be as dark as Mahogany or as
light as pale cream. |
SILVER - The silvering gene appears to be
similar
to
Chinchilla in
that it acts as a filter. But in this case it
filters black rather than light colour. A single dose of the silvering gene results in the dark silver
or
charcoal colour
dog and a double dose may be responsible for the lighter silver dog.
|
|
ON/OFF - I wish I could give you a name for
this modifier
but I
don't have an answer at this time. A gene such
as
this
"may" be
responsible for turning other modifiers on and off possibly playing a role in dogs who lighten
dramatically then deepen again as they mature. There is still much which is not yet known about
colour
genetics. There may be many more genes at play than are currently known or theorized about.
|
|
I don't have a name for this one either.
Similar to On/Off , the Plus/Minus may act on
other genes to either intensify and enhance expression or weaken and mute it and may be
responsible
for many
variations. There is still much which is not yet known about colour genetics.There may be many
more
genes at play than are currently known or theorized about.
|
|
Dorsal/Ventral - This may actually be
two or more separate gene modifiers. The Dorsal one appears to act on the upper areas of the
body
(head,
shoulders, back and tail) and the Ventral one on the lower areas of the body (Chest, belly
and legs). These genes are most noticeable on Sable dogs. The Dorsal areas soften less and
remain darker with a heavier overlay, while ventral areas lighten much more and may have no
dark overlay at all remaining at maturity. You may also see this on Brindles, Havana Browns,
Silvers and others. As adults, the dogs may be much darker on the top of their bodies than
underneath.
