112 ON COLOUR. Paet I. 



monises with blue, it has not necessarily the same effect with 

 white ; and blue and white (both cold colours) though their 

 effect is cold, are an agreeable concord without the assistance 

 of any warm companion. 



XIV. The colours that accord with each other may be 

 divided into different classes, as may those which are not 

 concords. Sometimes two colours agree by the harmony of 

 positive contrast (see p. 76) ; sometimes by the harmony of 

 analogy. Others require a third to make a complete com- 

 bination, without which they are deficient in effect ; which 

 frequently happens in consequence of having too near an 

 affinity to each other ; others, again, require more than one 

 companion to form a proper harmonious union ; and to such 

 colours in juxtaposition I apply the term " ivanting." 



Sometimes harmony is obtained by two colours, as orange 

 and blue; sometimes two colours will not form a concord, 

 without the addition of a third, to complete it ; occasionally 

 a concord is only to be obtained by a combination of several 

 colours ; and sometimes a colour, though it may not cause a 

 discord, fails to make an agreeable combination with any 

 other one or two colours, and is better by itself, as pink and 

 others already mentioned (pp. 105, 106). Sometimes it is 

 better as a ground (pp. 105, 106) than when in combination 

 with others of nearly the same quantity. Sometimes, on the 

 other hand, a colour does not look well alone, and requires 

 to be in combination with another, as scarlet, which wants 

 the contrast of blue, or some other colour. But even though 

 colours may be found to possess their full effect when alone, 

 they may also enter well into a large pattern composed of 

 numerous others, and even browns, buff, and many more 

 well suited for grounds, may be combined in a general de- 

 sign, provided they are inferior in quantity to the primary 

 hues. 



Two colours then agree — 1. By the Harmony of contrast:
