166 ON COLOUR. Pari I. 



15. A great quantity of the same colour in one part, and 

 little or none of it in another, are fatal to the general effect, 

 and disturb the balance of colours, (pp. 99, 147.) 



16. Large masses of one single colour should not catch the 

 eye ; it should receive, at the same moment, the combination 

 of several colours. The patterns should not be too large. 

 Spots and monotonous lines should also be avoided. It is, 

 however, allowable to have a mass, or ground, of one colour 

 in the centre, and a border of several colours round it. (p. 54, 

 § 37 p. 40; and Sect. XVIII.) 



17. Bright green may be well introduced to lighten up a 

 composition ; but not in masses, except as a ground ; and 

 when used in great quantity it is a sign of an artificial and 

 debased taste. In those compositions, however, which are to 

 be seen mostly by candlelight a greater proportion of green 

 may be used. (pp. 16, 17, 105, 106, 125, and in Sect. XIX.) 

 Green as a ground sometimes suits other colours, which 

 would not accord with it if interlaced together in a pattern ; 

 but it must be a glaucous green. (Of the best hue for this 

 purpose, see p. 105, note.) 



18. Greys, and some other neutral (or intermediate) colours, 

 answer well as a ground and soften the abruptness of contrasts 

 (as of black and white), when required, (p. 107.) 



1 9. Two of the primaries may harmonise better with each 

 other than another two of them ; and blue and red, or blue 

 and yellow, or red and yellow, accord in different ratios. 

 (p. 61.) So too there may be a greater or less degree of rela- 

 tionship between any two of the secondaries; and while 

 orange and green, or orange and purple, are both agreeable 

 in juxtaposition, purple and green are discords. The same 

 difference subsists also between the primaries and their 

 accidental (secondary) colours ; blue and orange harmonising 

 most agreeably by contrast, which cannot certainly be said of 

 red and blue-green. (See above, No. 6, and p. 74.)
