Adding warm colors to base of trees, still on dry paper, I went across this area to set the trees down. A few warm greens mixed with Arylide, ultramarine, Midnight, and Vitruvius blues were set side by side. Light yellow green areas show just a touch of summer we've left behind. More glazing on backlit trees, each tree being different from its neighbor, was done. This is a design principle called variation that I use a lot with each piece and keeps them from being boring.
