Those who have written on the practice of painting have always recommended the use of few colours for flesh. Reynolds and others quote even ancient authorities as recorded by Pliny, and Boschini gives several descriptions of the method of the Venetians, and particularly of Titian, to the same effect. "They used," he says, "earths more than any other colour, and at the utmost only added a little vermilion, minium, and lake, abhorring as a pestilence _biadetti, gialli santi, smaltini, verdi-azzurri, giallolini_."[2] Elsewhere he says,[3] "Earths should be used rather than other colours:" after repeating the above prohibited list he adds, "I speak of the imitation of flesh, for in other things every colour is good;" again, "Our great Titian used to say that he who wishes to be a painter should be acquainted with three colours, white, black, and red."[4] Assuming this account to be a little exaggerated, it is still to be observed that the monotony to which the use of few colours would seem to tend, is prevented by the nature of the Venetian process, which was sufficiently conformable to Goethe's doctrine; the gradations being multiplied, and the effect of the colours heightened by using them as semi-opaque mediums. Immediately after the passage last quoted we read, "He also gave this true precept, that to produce a lively colouring in flesh it is not possible to finish at once."[5] As these particulars may not be known to all, we add some further abridged extracts explaining the order and methods of these different operations.
