Now, as you are not bound to use anything for the decoration of your walls but simple tints, I will here say a few words on the main colours, before I go on to what is more properly decoration, only in speaking of them one can scarce think only of such tints as are fit to colour a wall with, of which, to say truth, there are not many.
Though we may each have our special preferences among the main colours, which we shall do quite right to indulge, it is a sign of disease in an artist to have a prejudice against any particular colour, though such prejudices are common and violent enough among people imperfectly educated in art, or with naturally dull perceptions of it. Still, colours have their ways in decoration, so to say, both positively in themselves, and relatively to each man’s way of using them. So I may be excused for setting down some things I seem to have noticed about these ways.
Yellow is not a colour that can be used in masses unless it be much broken or mingled with other colours, and even then it wants some material to help it out, which has great play of light and shade in it. You know people are always calling yellow things golden, even when they are not at all the colour of gold, which, even unalloyed, is not a bright yellow. That shows that delightful yellows are not very positive, and that, as aforesaid, they need gleaming materials to help them. The light bright yellows, like jonquil and primrose, are scarcely usable in art, save in silk, whose gleam takes colour from and adds light to the local tint, just as sunlight does to the yellow blossoms which are so common in Nature. In dead materials, such as distemper colour, a positive yellow can only be used sparingly in combination with other tints.
