The work of Mary Cassatt is made up of broken brushwork, bright colours, layering of paint and a vast colour palette. Cassatt often paints young women and children. James Abbott McNeill Whistler was born in America but spent the majority of his life within Europe. Whistler painted many monochromatic scenes of the river Thames in London during the early 1870s. This was a new aesthetic that inuenced many British, American and French artists. He uses a mute colour palette with variations on a single colour.
