The colour wheel
It was Sir Isaac Newton who created the first colour wheel which follows exactly the same configuration of colour as the horizontally represented visible light spectrum. The colour wheel remains a powerful aid to designers, photographers and creative artists of all kinds. The wheel displays how analogous colours (adjacent colours) work well in combination, as do complimentary colours (colours at opposite sides of the wheel). In the colour wheel example, the colour purple appears outside the visible wavelengths. This is because purple does not conform to a specific wavelength but is created by mixing wavelengths of red and violet.
Examples of nature follwing the rules of the colour wheel. The purple flower is complimentary to the green foliage as both colours lie at opposites on the wheel.
The yellow of the lemons lies adjacent to the green of the leaves making this colour combination analogous.
