The brushes are of different types. Each position of the brush conforms to a specific quality of the line, either sharp and precise or broad and quivering, the ink spreading in strong touches or thinning to delicate shades.
The colors are simple, of mineral or vegetable origin. Chinese painters have always avoided mixing colors so far as possible. From malachite they obtained several shades of green, from cinnabar or sulphide of mercury, a number of reds. They knew also how to combine mercury, sulphur and potash to produce vermilion. From peroxide of mercury they drew coloring powders which furnished shades ranging from brick red to orange yellow. During the T’ang dynasty coral was ground to secure a special red, while white was extracted from burnt oyster shells. White lead was later substituted for this lime white. Carmine lake they obtained from madder, yellows from the sap of the rattan, blues from indigo. To these must be added the different shades of Chinese ink and lastly, gold in leaf and in powder.

The brush-stroke in the painting of the Far East is of supreme importance. We know that this could not be otherwise if we recall that the characters in Chinese writing are ideographs, not actually written, but rather drawn. The stroke is not a mere formal, lifeless sign. It is an expression in which is reflected the beauty of the thought that inspired it as well as the quality of the soul of him who gives it form. In writing, as in painting, it reveals to us the character and the conception of its author. Placed at the service of certain philosophical ideas, which will be set forth later on, this technique was bound to lead to a special code of Aesthetics. The painter seeks to suggest with an unbroken line the fundamental character of a form. His endeavor, in this respect, is to simplify the objective images of the world to the extreme, replacing them with ideal images, which prolonged meditation shall have freed from every non-essential. It may therefore be readily understood how the brush-stroke becomes so personal a thing, that in itself it serves to reveal the hand of the master. There is no Chinese book treating of painting which does not discuss and lay stress upon the value of its aesthetic code.
II. REPRESENTATION OF FORMS
It has often been said that in Chinese painting, as in Japanese painting, perspective is ignored. Nothing is further from the truth. This error arises from the fact that we have confused one system of perspective with perspective as a whole. There are as many systems of perspective as there are conventional laws for the representation of space.
