205. 1. _Red, Yellow_, &c. 2. _Black, Red, Yellow, Black_. 3. _Black, Red, Black, Yellow, Black_, &c. The two last arrangements appear to me superior to the first, and many persons would prefer them to the arrangement in which _white_ replaces _black_. I cannot too strongly recommend the arrangement 2 and 3 to artists, for whom these observations are especially designed. 206. 1. _Red, Blue_, &c. 2. _Black, Red, Blue, Black_. 3. _Black, Red, Black, Blue, Black_, &c. No. 2 is preferable to No. 3, because there are too many sombre colours in the latter, and because these differ too much from the _red_. The effect of _black_ upon the binary arrangement, _red_ and _blue_, is inferior to that of _white_. 207. 1. _Red, Violet_, &c. 2. _Black, Red, Violet, Black_, &c. 3. _Black, Red, Black, Violet, Black_, &c. The _red_ and _violet_ injure each other, it is therefore advantageous to separate them by _black_; but the latter does not produce so good an effect as _white_. It is difficult to say whether No. 3 is preferable to 2; because, if there be in the latter _red_ near _violet_, this defect is more than compensated in 3, by the predominance of sombre colours over the _red_. 208. 1. _Orange-Yellow_, &c. 2. _Black, Orange-Yellow_, &c. 3. _Black, Orange, Black, Yellow, Black_, &c. The _orange_ and _yellow_ being very luminous, the _black_ allies itself to them very well in the arrangement 2 and 3; and if the arrangement, _white, orange, yellow, white_, be preferred to No. 2, I think that in the arrangement 3, the _black_ produces a superior effect to the _white_. 209. 1. _Orange, Green_, &c. 2. _Black, Orange, Green_, &c. 3. _Black, Orange, Black, Green, Black_, &c. _Black_ combines well with _orange_, and with _bright green_. In like manner it combines well with _orange_ and _yellow_. If, in the arrangement 2, _white_ be preferred to _black_, I think it cannot be in 3. I recommend to artists the combination of _black_ with the binary arrangements _orange_ and _yellow, orange_ and _green_. 210. 1. _Orange, Violet_, &c. 2. _Black, Orange, Violet, Black_, &c. 3. _Black, Orange, Black, Violet, Black_, &c. _Black_ does not combine so well as _white_ with _orange_ and _violet_, because the proportion of dark colours relatively to _orange_, a very vivid colour, is too great. 211. 1. _Yellow, Bright Green_, &c. 2. _Black, Yellow, Green, Black_, &c. 3. _Black, Yellow, Black, Green, Black_, &c. _Yellow_ and _light green_ being luminous colours, _black_ combines very well with them; and if in the arrangement 2 the effect of _white_ be preferred to that of _black_, I think that it cannot be in the arrangement 3. 212. 1. _Yellow, Blue_, &c. 2. _Black, Yellow, Blue, Black_, &c. 3. _Black, Yellow, Black, Blue, Black_, &c. If the arrangement 2 be preferable to 3, I think it inferior to 1. The _black_ does not appear to combine so well as the white in the group _yellow_ and _blue_.
