Canadian artist, Lynn Cassels-Caldwell further expands on this idea in a post titled: The power of PURPLE!
She writes: I had been thinking about how I could pop my model's colour, and Sarah Minkiewicz-Breunig posted a great article about using unconventional colour mixes. I was so inspired! So I did some experimenting with purple for the 2nd layer. I worked it out carefully on my palette. I'm thrilled it turned out perfect for this guy! I normally would have used just Van Dyck Brown for the darks, but the purple mix was so much livelier.
Here is a colour progression showing the body colours with the purple mix beside the Van Dyck Brown, which looks dull by comparison.
Thanks for that colorful reminder, ladies. I'll be sure to work it into my own
blogging finishwork soon!
