Brighter, clearer, purer tone than can be obtained by mixing colors on the palette. Blues are made from colbalt, and yellows from iron, antimony, zinc, ect. ; and the union of either of these latter with the former will not produce a green oxide, nor will the combination ever give satisfactory greens.
The blues and carmines are more manageable ; but there is not advantage even here, for should a satisfactory tint be obtained at random, the fact that it was the result of mere chance preclude duplicating it with any degree of certainty. However close the approximation may be. haphazard amalgamations are of no real benefit ; and china makes certain demands, mechanical and technical. that must be respected.
Another error into which the amateur is likely to fall, if not suitably provided with a full complement of colors, is the ineffectual attempt to make a thin wash of a dark color do duty for a light shade, and vice versa. For instance, carmine, rose, or English pink must be applied very thinly to produce a pure delicate pink, as in a pink rose. But a deep pink rose can never be painted by using the same color heavier. When the darker rose is to be painted, a darker color must be used. such as ruby. With carmine and ruby, almost any shade me be obtained ; but used separately, each has its limitations. A heavy , dark color, put on
