This colour wheel (known as
a Brewster/Prang colour wheel) has been produced with coloured pencils, using
primary colours of Red, Yellow and Blue.
The wheel organises the colour pigments into primary, secondary and
tertiary hues. The secondary hues are
orange, green and violet, the tertiary hues are red-orange, yellow-orange,
yellow-green, blue-green, blue-violet and red.
These colours are all
tertiary hues, the first being red-violet, the second violet and the third
blue-violet. Red was added to blue and
then white until the tone was the right hue.
Yellow and Blue are the
primary colours here. I added blue to
yellow to obtain the tertiary yellow-green and white to blue until it was the
correct hue.
In this example Yellow, Red
and Blue are the primary colours used to give theses tertiary hues of
yellow-green and yellow-orange.
The below images demonstrate
the effects of different lighting on the colour selections.
The image below is taken in
bright sunlight which has high levels of illumination making the colours seem
less saturated, or lighter.
The same image has been photographed (below) in subdued lighting, lowering the illumination has darkened the colours values
and neutralised their hues.
