I wound up abandoning this class part way through because I was distracted by kayaking and I only got back to it near the end of the summer when I was in a hurry to get ready for the final class. I may revisit the exercises since I know I need more work here. This is the 2nd class in the series by Ian Roberts.
We started with black and white only and then, later, added ochre yellow to represent ‘warmth’ while black and white remain ‘cool’. I think one or two added a little UM blue as well, for extra coolness.
