TAXIDERMY AND MODELLING 



crimson lake (a fine but very fugitive colour now superseded 

 by alizarin, which is coarser but permanent) and flake white, 

 faded to a bluish drab. 



It will be seen by this that, although " permanent blue " 

 (an impure ultramarine) was used, it was killed by the fugitive 

 colour, which, in turn, was killed by the lead white ; and in this 

 and all similar instances the fact must be thoroughly grasped, 

 that a " permanent " colour is only permanent per se, or when 

 mixed with other permanent colours, and is fugitive when mixed 

 with any fugitive colour, although there are some which "hold 

 up " for a certain time a colour known to be fugitive. 



As a general rule it must be remembered that one pigment 

 unmixed is absolute purity ; two mixed are permissible and 

 agreeable ; three mixed are less pure and border on grey or 

 brown ; and four mixed are dirty, or perilously near to black ; 

 also that, the less mixing or " worrying " pigments undergo, 

 the greater the purity of the combinations. 



In these pages, a colour in the abstract is spoken of as a 

 " hue " ; when mixed with white it is a " tint " ; whilst " tone " 

 is relative light and shade, without reference to tint or hue.
