colours tetrad

TETRAD COLOUR SCHEME is  2 sets of contrasting colours

eg. rust/turquoise, lime/magenta

or rust/turquoise, Purple/yellow or Purple/yellow, blue/orange


To help you remember what is a tetrad scheme, imagine a square.

When you join the shape of 2 contrasting colours on the colour wheel you make a square.

The word tetrad is also used in the metric system defining land areas.  A 2km x 2km square is called a tetrad.

A tetrad is also used in microbiology to define clusters of four cocci bacteria, which are shown as 4 circles arranged in a square.

A tetrad scheme does not need to be high chroma impact colours

Add some natural elements -think of plants and timber as part of the colour scheme
