The third week was reds. It's rather a long time ago now - I've been to Bathurst and the UK and back, then New Zealand and back. So much to write about...
I find reds fascinating. Adjust the bias from orange to purple and the mixing possibilities change dramatically. I tend to choose the semi-transparent reds though the cadmiums are excellent pigments. I like to use three reds rather than the standard warm and cool - a warm, a crimson and a rose red - great mixing options there.
I love the dramatic blacks and greys you can mix with a good strong crimson and phthalo green. And phthalo blue with a warm red won't make a purple. Fascinating :-)
My students had a go at painting a still life filled with red objects and using greens to create the shadow colours.
