Painting the Purple Iris
Step Seven: Altering reality
My original photo had a background of a sunlit brick wall. I decided the bricks would make the painting too busy and opted to use a dark mixture of Pthalocyanine Blue and Burnt Umber to indicate a deep shadow area behind the entire group of flowers and foliage. I varied the mixture as I painted the background.
These two colors can give you deep dark blues, rich greens and warm dark browns as you mix them in different quantities.
