This week I just took a little time exploring how two reds, one closely related to orange, Vermilion and the other Alizarin Crimson, closer to purple, mixed and related to two very different greens, Sap Green which is much more yellow that Phthalocyanine Green which leans toward blue.
You may have different greens and reds in your paint box. Take some time to discover how near to orange or purple s each red is and how near to yellow or blue each green is.
Viridian, Phthalocyanine Green, Cobalt green and Prussian Green are all examples of greens nearer to blue. Sap Green is a more yellow green and Hooker’s Green is much bluer than Sap Green but more yellow than Phthalo Green.
Vermilion, and Cadmium Red Pale are much nearer to orange than Crimson Alizarin, Quinacridone Rose and Magenta and you may have other reds which are somewhere between the two.
Before homing in on the green and red pigments you choose for your painting subjects this week find which combinations will be best suited by experimenting a little.
In each example make a note of how the red and green pigments are being employed and how they interact. Observe how red looks when surrounded by dark, pale tones, by similar hues and by complementary colours both pale greens, dark greens, yellow greens and bluer greens.
Choose only two from the following list and make two paintings incorporating one in each. That doesn’t mean to say the other items won’t be present but I would like you to have one main theme for each painting, just as a story may involve one main character and a couple of supporting roles. Don’t feel you have to do two paintings. One well thought out composition is really worthwhile.
A bright red line winding a bright way through a green and a very close blue green of similar tone
A painting with very equal amounts of red and green
A painting that is almost all green with a tiny flash of red or a painting with a large area of red with a little green.
A painting where the colours adjacent to each other are just slightly different but span the range between red and green. This should involve a lot of mixing either wet in wet or on the palette/overlaying colours.
A painting with huge tonal differences.
You may use white pure in areas and in mixes, and your paintings may be representational or abstract. The medium is up to you. Try to make dark tones by mixing the appropriate reds and greens and use black only if essential.
Think very carefully about how many greens you wish/need to work with and how many reds. The illustrations will give you some idea of the scope of using only four pigments but you may wish to explore lots of greens in a painting and only one red for instance. Try to have a reason for your choices.
After a while it becomes intuitive to just go for the “right” colour knowing how it will appear on its own and in mixes, and you will definitely begin to enjoy using some pigments more than others. I firmly believe that individual colour choices and combinations form as much of the identity of an artist as the shapes and lines he produces. (“he” being used in the universal mankind sense here.) Think this has already been born out in the last few weeks by those who prefer orange and blue to yellow and violet and vice versa!
