For this exercise, I was to draw a circle divide it into 12 parts and and mix the colours from Chevreuls colour circle or wheel beginning with primary re, red-orange and so on.
Next I had to consider the twelve colours from Chevreuls colour circle and lay each colour next to its opposite or complementary on a grey ground. Try to match the darker tone to the lighter by adding white. Then I had to make mixtures of each pair of complementary colours and describe the resulting colour.
One thing that I have notice was I didn’t seem to be able to match tones as easy on a grey ground I found this very difficult as can be seen its easier when I look at the colour wheel which does emphasis Chevruels view that adjacent colours can alter the tone. I do a lot of work in black and white and found it really disturbing that I find it so hard to do with colour on a grey.
As can be seen with the mix of the pair of complementary colours I managed to get the tone a little better, hopefully a learning curve and not letting the grey ground influence my tone. When mixing complementary colours in relatively even amounts the colours in the main went to a version of brown, well nearly all, blue and orange was more a grey because of the lack of red pigment and the yellow purple to green beige in relation to the amount of red in the purple. I have noticed Complementary colours are just that and complement one another, enhancing each other’s visual appearance.
