I have a reference photo of a peach rose that I have been wanting to do for awhile. I usually get so "lost" in the petals of a complex rose that I decided to start with an underpainting of blue/gray for the rose, stems, buds and foliage and then add color later. I have done this successfully when painting monochromatic sepia paintings, but never with using it strictly as an underpainting, so it is an experiment to see what happens. So far, so good. This is almost a full sheet painting, painted to fit into a 24 x 36-inch frame.
I will next go on to underpainting the stems and front leaves. the background foliage will probably be done more loosely and somewhat impressionistically, we'll see. More to come....I hope!
