Beagles appear in a range of colours. Although the tricolour (white with large black areas and light brown shading) is the most common, Beagles can occur in any hound colour. Tricoloured dogs occur in a number of shades, from the "Classic Tri" with a jet black saddle to the "Faded Tri" where the faint black markings are toned with brown. Some tricoloured dogs have a broken pattern, sometimes referred to as pied. These dogs have mostly white coats with patches of black and brown hair. Two-colour varieties always have a white base colour with areas of the second colour. Tan and white is the most common two-colour variety, but there is a wide range of other colours including lemon, a very light tan; red, a reddish, almost orange, brown; and liver, a darker brown. Liver is not common and is not permitted in some standards; it tends to occur with yellow eyes. Ticked or mottled varieties may be either white or black with different coloured flecks (ticking), such as the blue-mottled or bluetick Beagle, which has spots that appear to be a midnight-blue colour, similar to the colouring of the Bluetick Coonhound. Some tricolour Beagles also have ticking of various colours in their white areas.
