Oh, I am loving the color in this - glorious color! The sky is a mixture of Winsor and Newton Vermilion (a pinkish red) and Rembrandt Vermilion ( an orange red) with buff titanium to lighten and a dash of white for good measure. This one I have titled Quantum Poetry. 36x24 oli on stretched canvas. Please click on the photo to view it larger - I am sure you will enjoy it more!
