Complementary Colours

Which are the complementary colours?
     The two colours on opposite sides of the colour wheel.


     The complementary colour of a primary colour (magenta, cyan, and yellow) is the colour you get by mixing the other two (magenta + cyan = purple; cyan + yellow = green; magenta + yellow = red). So the complementary colour for magenta is green, for cyan it's red, and for yellow it's purple.    


Why is it imortant to know the complementay colours?
    Two complementary colors are those which offer together best possibilities of contrast, even though they are very violent visually combining two complementary colors.


 What happens if we mix two complementary colours? 
     The colour will be greyish. That was one of the main discovery made by the impressionist painters: Grey and dark tones are produced by mixing complementary colours. In pure Impressionism the use of black paint was avoided.
     They also knew that when placed next to each other, complementary colours make each other appear brighter, more intense. The shadow of an object will also contain its complementary colour, for example the shadow of a green apple will contain some red.
