About The Coloured Horse & Pony Society (UK)
WHAT is a “COLOURED” HORSE or PONY?
The definition of a “coloured” horse or pony is one whose coat colour is either
(piebald) or white and any other colour (skewbald), e.g. bay, roan, chestnut; with a patch of naturally
occurring white coat. This white patch must be on the body above the level of the stifle or elbow,
excluding any face markings. Any white marking below this does not qualify. Manes and tails may
also be white or have white in them. Appaloosa animals with belly markings do not qualify.
If there is any doubt as to whether an animal is classified as coloured, photographs showing all
markings should be submitted to CHAPS (UK) Administration for referral to Council at the next
available meeting. If further clarification is required a representative of CHAPS Council will be
required to inspect the animal at a mutually agreed location. Should further verification prove
necessary, DNA testing will be required for the presence of the “colour” gene.
Animals with the fading colour gene, common with grey and whites, when colour definition is
not apparent will be known as “historical” coloureds. It is at the discretion of the owner whether or
not an animal which is historically coloured should be shown.
Within the categorisation of what is phenotypically (seen to be or looks)
“coloured” CHAPS recognise the following:
TOBIANO (Toh-bee-ah’no) appears to be white with large “spots”
(or “patches”) of colour, often overlapping, on animals
with a greater percentage of colour than white. Spots
of colour, typically, originate from the head, chest, flank
and buttuck, often including the tail. Legs are
generally white, giving the appearance of a white horse with
large or flowing spots of colour. Generally white crosses the centre
of the back between the withers and tail.
TOBIANO COLOUR MARKINGS
OVERO (O-vairo) appears to be a coloured (where
coloured is meant here to signify any other shade of coat than
white) horse with white markings. The spots
of white appear to be jagged and originate on the
animal’s side or belly, spreading towards the neck, tail,
legs and back. The
colour (any other shade than white)
appears to frame the white spots. An
overo often has a dark tail, mane, legs and backline. Faces
are often white. Some overos show dark
legs with splashy white markings seemingly made up of round
lacy white spots. The location of the
white never crosses the backline.

CLASSIFICATION of MARKINGS
Tobiano and Overo markings are also classified into six categories,
as shown above. The category of
markings is detailed at the end of your horse’s ID number of the
passport, e.g. T2EG where T2 denotes
the coat pattern (category of markings, in this case Tobiano type 2),
E denotes the estimated adult
height (see “Height Categories”) and G denotes the sex (in this case,
gelding); or O3CS (which in this
case O3 would be Overo pattern 3), C would be estimated adult height
and S would denote stallion.
Height categories are denoted as follows (and are taken as being at maturity):
Not exceeding 128cms (0-12.2hh) = A.
Exceeding 128cms but not exceeding 138cms (exc 12.2hh but not exc 13.2hh) = B.
Exceeding 138cms but not exceeding 148cms (exc 13.2hh but not exc 14.2hh) = C.
Exceeding 148cms but not exceeding 158cms (exc 14.2hh but not exc 15.2hh) = D.
Exceeding 158cms but not exceeding 168cms (exc 15.2hh but not exc 16.2hh) = E.
Exceeding 168cms but not exceeding 178cms (exc 16.2hh but not exc 17.2hh) = F.
Exceeding 178cms (exc 17.2hh) = G.
These letters form part of each animal’s individual Basic Identity Number and follow the appropriate
code for markings (e.g. T2E where “E” indicates the estimated adult height as shown above (older
passport identification numbers would be shown as “/T2E/”) which will appear on the Passport.
