The 12 part colour wheel above is based on the three primary colours ( Red, Yellow and Blue ) placed evenly around a circle.Between the three primaries are the secondary colours (Green, Orange and Violet) which are mixtures of the two primaries they sit between.The tertiary colours fall between each primary and secondary. Between yellow and orange, for example, is yellow orange, between blue and violet is blue violet and so on

Johannes Itten devised a 12 part colour wheel, as it offers a much better understanding of the interaction of colours

Colour is the most striking of all the elements, and its impact is enormous. Complementary colours are those opposite each other in the colour wheel, such as red/green. blue/orange and yellow/violet. Put these colours together and your eyes with almost sting as these colours are equal in colour value.Use these combinations to show off a special piece of plant material.

Tryad:A colour tryad is a colour taken from 3 sides of the wheel, If this is blue/yellow/red you will create a circus, child's room effect, fun, bright and cheerful.	The dark side: Pick only colours from one part of the colour wheel such as the blues/purples/greens you'll get dark effects, watery, night, mystical,relaxing .	complementary colours:Choose two colours side by side from the wheel and one from opposite and you'll get contrast and harmony working well together and the opposite colour balances the other .
hot colours Choose red/orange/yellow and show heat, light, zing, wow factor and stimulation	Compound colours: Compound colours contain a mixture of the three primaries. All the browns, khakis and earth colours are compound colours.	Take a lesson from Nature: Any flower will give you successful colour combinations and the proportion to use of each colour. More...
The magic of lime green: Lime green in any flower will immediately add excitement to darker colours. Chrysanthemums in lime green are the easiest to find.	If you are using all one colour... use textural contrast and different forms to add more interest as well as the tints, tones and shades of that colour.	different proportions: Yellow and purple are complementary colours but don't use them in the same proportion to achieve a more successful design.
Pure hues: Using pure hues together will result in a very strong, masculine design.	soft tints: The soft tints and pastels of any colour will produce a more feminine arrangement	Tints, tones and shades: For a completely unified look pick one colour and choose all its tints(white added), tones (grey added) and shades (black added) with green lightly sprayed to blend.
