182. 1. _Yellow and Violet_ form an arrangement which, as regards depth of tone, is most distinct, since the least intense or lightest colour, the yellow, is separated from the others. Because of this great contrast of tone, the deep, but pure, greenish-yellow combines better with light violet, than light yellow and deep violet. 2. The arrangement, _white, yellow, violet, white_, &c., appears to me inferior to the preceding arrangement (1). 3. The arrangement, _white, yellow, white, violet, white_, &c., seems to me inferior to 2. C. _Ternary Assortments of Colours not complementary with White._ 183. 1. Red and orange do not accord well. 2. The arrangement, _white, red, orange, white_, &c., is scarcely preferable. 3. The arrangement, _white, red, white, orange, white_, &c., is not so bad as the preceding, because white being favourable to all the colours, its interposition between the colours which injure each other, can only produce an advantageous effect. 184. _Red and Yellow_ accord pretty well, especially if the red is purple-red rather than scarlet, and the yellow rather greenish than orange. 2, The arrangement, white, red, yellow, white, is preferable to the preceding. 3. The arrangement _white, red, white, yellow, white_, is still better. 185. 1. _Red and Blue_ accord passably, especially if the red incline rather to scarlet than to crimson. Deep tones are preferable to light ones. 2. The arrangement _white, red, blue, white_, &c., is preferable to 1. 3. The arrangement _white, red, white, blue, white_, is preferable to the second. 186. 1. _Red and Violet_ do not accord well, yet they are found in some natural productions, as the sweet pea. 2. The arrangement _white, red, violet, white_, is not so bad as the preceding. 3. The arrangement _white, red, white, violet, white_, is preferable. 187. 1. _Orange and Yellow_ accord incomparably better than red and orange. 2. The arrangement _white, orange, yellow, white_, is agreeable. 3. The arrangement _white, orange, white, yellow, white_, is not so good as 2, and perhaps 1, because there is too much white. 188. 1. _Orange and Green_ do not accord well. 2. The arrangement _white, orange, green, white_, is preferable to 1. 3. The arrangement _white, orange, white, green, white_, is perhaps preferable to 2. 189. 1. _Orange and Violet_ accord passably, yet not so well as orange and green; the contrast, in the latter case, is greater than in the arrangement orange and violet. 2. The arrangement _white, orange, violet, white_, &c., is preferable to the preceding. 3. The arrangement _white, orange, white, violet, white_, &c., is preferable to 2. 190. 1. _Yellow and Green_ form an agreeable combination. 2. The arrangement _white, yellow, green, white_, &c., is still more agreeable. 3. The arrangement _white, yellow, white, green, white_, &c., is inferior to the preceding, and perhaps to the first. The inferiority of 3 seems to me to be caused by too much light for the _green_.
