Just a small floral sketch to get me back in the mood for painting. I didn't have any orange paint, but as it turned out the cadmium yellow and cadmium red mix beautifully into all shades of orange. Which brings me to something I have been wondering about... It seems that in the artists circles using green paint is considered a weakness. "Real artists mix their greens" Yet there doesn't seem to be a similar attitude towards the other secondary colors like orange and purple. Is there any rational explanation to that? For example that there are reliable single pigment oranges, like cadmium orange, while premixed greens have a poor lightfastness. Or is there some dose of snobbishness in all that?
