Seeing the act of painting as arranging forms and colors on a flat surface meant that artists now saw the 'formal' elements of painting (color, space, composition) as the true subject of their work. This notion marked the beginning of modernism in art. Fauvism placed emphasis on large, simplified forms and bright, "unnatural" color - color which existed independently of most local color (the 'actual' color of objects). This approach concentrated on, for example, color relationships as the most important concern - how colors affected one another visually, and combined to create the 'reality' of the image, rather than trying to depict the objective world. Matisse began with still lifes and interiors which still contained some observation of nature in the drawing of objects, with some 'flattening' of forms and of the canvas surface. As he matured as an artist, the forms became more and more simplified, and the images became less concerned with 'correct' drawing. Eventually, his images appear to have been only cursorily drawn and painted - just the essential parts were distilled from the image. There was no use of linear perspective to indicate spatial depth in this new painting; on the contrary, Matisse used his curvilinear forms and bold decorative patterns to emphasize the flatness of the canvas surface. There was also no blending of colors - they were placed flatly against one another, avoiding the 'soft' look of blended color and the 'natural' look of this method of depicting three dimensions.
