Light-dark contrast is one of my favourites.  It is a contrast in value of colours and is a common way to decorate a room.  There are 4 main categories of light-dark contrast:

  • In a monochromatic contrast there is one colour in varying tints and shades.


  • A polychromatic contrast requires at least two different colours that are also different in value.


  • An achromatic contrast is one in which there are only black, white and grey.

  • There are also two combinations possible: either achromatic combined with monochromatic or achromatic combined with polychromatic.
