Wherein particularly lies the Art of Colouring ?
Beside the Mixture of Colours, such as may answer the Painter’s Aim, it lies in a certain Contention, as I may call it, between the Light and the Shades, which by the means of Colours, are brought to Unite with each other ; and so to give that Roundness to the Figures, which the Italians call Relievo, and for which we have no other Name : In this, if the Shadows are too strong, the Piece is harsh and hard, if too weak, and there be too much Light, ’tis flat. I, for my part, should like a Colouring rather something Brown, but clear, than a bright gay one : But particularly, I think, that those fine Coral Lips, and Cherry Cheeks, are to be Banished, as being far from Flesh and Blood.
