SCALE OF COLOUR VALUES 47 



hair it so appeals to artists as to be generally- 

 reserved for the most sacred portraiture. In 

 horses, it so appeals to horsemen as to rank 

 next bright Bay in the scale of values. 



The Brown Horse. This is a colder, 

 washed-out tone of Bay. 



The Black Horse. Among feral and range 

 horses, those of the very darkest bay and "brown 

 become brown-black under the summer sun- 

 light. True black is unknown among outdoor 

 horses, and can only be due to special selective 

 breeding. 



The Grey Horse. All greys are obviously 

 crossed between white and the various whole 

 colours. 



The primary horse colours are Dun and Bay. 



The secondary colours are white, black, 

 grey, chestnut, and brown, whole colours 

 shared by human and horse folk. 



The tertiarj^ colours are crosses of white 

 with Bay, Dun, black, chestnut, brown, which 

 produce the various roans. Beyond that the 

 human hair withdraws from competition. 



The quarternary colours are crosses of white 

 with whole roans, producing strawberry and 

 cream roans, and roan-balds ; while a peculiar 

 mixture of white with black, bay or chestnut, 

 gives us the piebalds and skewbalds.
