§55 VII. COLOURS IN JUXTAPOSITION. 101 



that the deeper one overpowers that of a lighter tone ; the 

 same occurs when they are of a similar kind ; and the effect 

 of the weaker one being diminished, it looks paler than it 

 really is ; while that of the stronger one is increased. Thus 

 a light orange, close to a scarlet, is overcome by it; and a 

 broad line of orange between two yellow ones assumes so 

 much deeper a tone that it will actually appear red ; and the 

 same line placed between two red ones will be reduced in 

 appearance to yellow. Allowance must therefore be made 

 for these changes, when such colours, or tones of colours, are 

 combined in a pattern. 



VII. This should also be borne in mind, that two colours 

 sometimes borrow from each other, in another ivay, when in 

 juxtaposition; and a red in the midst of a ground of yellow 

 (or with yellow interwoven with it) approaches to an orange, 

 or a scarlet, in appearance. This borrowing from each other 

 is not only the case in colours of more or less analogous 

 nature, but also in those which are contrasts; as blue and 

 red, which, as I have already shown, borrow from each other 

 when in contact, and appear purple unless separated by a 

 third colour. And here I must repeat, that there are cases 

 where a light and deep tone of the same colour, or of two 

 analogous colours, may with advantage be placed near 

 together, in combination with many others ; and in a carpet, 

 or piece of drapery, a bright with a deep yellow, two tones of 

 red, or of blue, or a yellow with an orange, lighten up the 

 composition ; and are often very effective, both when near 

 and even when at a distance from each other. The use of 

 light with a deep blue is also of great service by candlelight, 

 the latter giving to its companion a more evident appearance 

 of blue, which it is apt to lose at night, when, from its 

 absorbing so much light, it assumes a dark hue ; and a dark 

 blue actually looks black. White combined with blue has 

 also the effect of restoring its blue appearance by candlelight,
