I was re-reading Kevin McPherson's first book about plein air painting and he stressed the need to accurately represent color by using a white paper as a reference, or a punched hole in a viewfinder to compare the value of the hue. It was an interesting exercise to always be comparing a color to the color next to it, or the contrast between the apple's edge and the background. I also switched to a halogen spotlight hoping to work in a cooler, less yellowing light. The more I looked, the more colors I saw. This was not a quick process, so my daily painting went over onto one more day.
