MIXING INTERMEDIATES
Intermediate purples provide a further array of colours different to
those in the bright and dull mixes. For example, pure Phthalo Blue

Quite by chance I discovered that M Graham’s Cadmium Red
mixed with Winsor & Newton’s Winsor Blue (Green Shade)
created similar purple-tinged greys, but the mix separated. Used
carefully here, the separation creates an interesting variety of
distinct reds and blues within the clouds.
I would suggest that our six-colour system gives us a good
balance between the possible colours we can mix and
remembering how to actually mix them. Pointillism used
optical mixing in much the same way as the printing process
and it is generally considered that the blended colours are
brighter and more vibrant than if physically mixed.
