do~). Its varieties are the lead-grey (plumbcus), which ap- 

 proaches near to the bluish; and the smoke-grey (iiebulosus)^ 

 which goes more into a brown. The mouse-grey also {muru 

 nus) is a soiled variety of the brownish-grey. 



3. The black colour (niger) has as its ground-tone the full 

 or coal-black {ater). In Greek compounds we express this 

 by the v/ords mela- or melano^. 



If the black passes somewhat into a greenish, it is called 

 raven-black {pullus) ; if it passes into a brownish, it is called 

 pitch-black (pweus'). 



4. The brown colour {brunneus) has as its ground-tone 

 the chesnut-brown (badius). If it falls more into the red, it 

 is reddish-brown (fuscus, in Greek compounds p?i<3&o-). If 

 it goes more into a yellow, it is liver-brown ; and when a mix- 

 ture of reddish is added, it becomes rust-coloured (ferrugi- 

 neus ). 



If the brown colour is pure and somewhat splendent, it is 

 said to be spadiceus. If it is quite dirty, and passing into 

 black, it is said to be smoky (fuligineus). If along with this 

 smoky state, it is also mixed with undefined shadings of co- 

 Jour, it is said, generally, to be lurid {luridus). 



5. The yellow colour {luteus, in Greek compounds {rantho-,) 

 has as its ground-tone the golden-yellow (aureus, in Greek 

 compounds cJiryso-). This is the same with the citron-yellow 

 {citrinus). 



A paler shade is denominated, generally, Jiavus. More 

 exactly defined varieties are the wax-yellow (cerinus), the 

 sjilphur-yellow {sulphur eus), and last the straw-yellow {stra- 

 milieus), which approaches pretty much to the white colour, 

 ^iid is hence denominated by a Greek compound ochroleucus. 

 The dark-yellow approaches either to the red or to the brown. 

 It is generally called tawny (fulvus ). Dark-yellow, with 

 reddish-brown, is called helvolus. Aurafitiacus, is dark-yel- 

 low, passing somewhat into a reddish. Saffron -yellow (cro- 

 ceus) is the distinctly intermediate colour between red and yel- 

 low. 



Jf the yellow is soiled and pale, it is called Isabella colour,
