Colour Theory
 
Primary Colours Colours at their basic essence; those colours that cannot be created by mixing others.
Secondary Colours  Colours achieved by a mixture of two primaries.
Tertiary Colours  Colours achieved by a mixture of primary and secondary hues.
Complementary Colours  Colours located opposite each other  on a colour wheel.
Saturation tells how pure or full a colour is
Value tells how intensive,  or light a surface is
Changes in value, whether sudden or gradual, can add greatly  to the visual impact of art forms. Changes in value can also be  used to help the artist express   an idea.
Saturation and Value
Shade:  A hue produced by the addition of black.   Tint:  A hue produced by the addition of white.
Warm and cool colours

Triadic Relationship  Three hues equally positioned on a colour wheel.
 
La Mousmé  , 1815 - Vincent Van Gogh.
Simultaneous Contrast  Notice how the red on the right responds to its association with blue
Another example Identical colors appear to shift when framed by different backgrounds or patterns. This is called "simultaneous contrast" and has a variety of affects on how we see things.
The round dots are all exactly the same color gray. I merely created the one on the extreme right and then copied it to each of the darker rectangles.
