Colour grouping and usage:
1 Descriptive – blue sky, green grass, yellow sun etc.
2 Monochrome – all one Hue or colour.
3 Arbitrary – any random or intentionally random grouping of colours.
4 Analogous – adjacent colours on colour wheel.
5 Complimentary – opposite colours on colour wheel – e.g. red and green, blue and orange, yellow and purple.
There are values in all colours.
Colours can be used to construct or to express.
Colour is used on the flat picture plane to give spacial references – warm advancing and cool receding – to create depth and volume.
Swing – Renoir; La chat aux poissons rouges – Matisse;
Constructive use of colour:
1 Use values to create sense of volume – 3D quality – by manipulation of chromatic values to give roundness. Renoir used colour values for volume, e.g. in SWING he used deep shade of orange for the shadows.
2 Balance composition with colour, by relating contrasts of colour, e.g. blue square to blue triangle.
3 Unify composition with uniform background, especially if mildly abstract. Colour can also be used as directional lines to the focal point.
4 Colour identifies the subject matter, e.g. sky is blue, grass is green, by the change of colour between objects. This is illustrating with colour.
Weeping Woman – Picasso
Expressive use of colour:
1 Colour is used to create a mood, e.g. sultry or peaceful.
2 Colours express emotions, e.g. happy, sad. Happy paintings by Matisse, anguish in Picasso’s WEEPING WOMAN, sorrow in his Blue Period.
3 Colour is used to symbolise ideals, e.g. red, white and blue for patriotism; gold, blues and mauves for the Heidelburg School; blue dress, white veil, and gold halo in religious paintings.
4 Colour has an aesthetic quality all its own – it can be used in its own right, for its own appeal, its harmonies and its contrasts.
