In this example, Picasso has treated line and colour as independent. Black lines define the features of the sitter, outlining the hair, eyes, nose, mouth, and the shape of the neck and shoulders. However, these lines foil to contain the non-naturalistic colours that have been randomlt applied to model the face. Thus, Picasso odds drawing to his conflation of painting and sculpture. The bold, red line running down the centre of the face also makes a reference to Henri Matisse's (1869-1954) famous Portrait of Lydia Delectorskaya.
