Optical mixing of colourscolourOptical mixing of colour means that a mixed colour is suggested without actually mixing colourstogether. We distinguish pointillistic and glazing colour mixing.Pointillistic mixingPointillism means painting with dots. To obtain agreen colour we do not mix yellow and blue paint,but paint yellow and blue dots close together on asurface. The surface will then give the impression ofbeing green. The smaller the dots the morecomplete the mixture will appear (ill. 28).Here too complementary colours make the mixedcolour unsaturated (dirty).[ 28]If we combine coloured dots with white, black orgrey ones, brightness and saturation are affectedin the same way as in ordinary mixing (ill. 29).[ 29]Even without black dark grey colours can besuggested through pointillism, although the resultwill never be as dark and unsaturated as incomplete mixing (ill. 30).pagen 21[ 30]
