I painted this 36″ x 12″ Acrylic from a photo taken a few years ago. I used just three colours (with titanium White) for the sunset colours: Cadmium Orange, Cobalt Blue, and Alizarin Crimson. I love the purple that Cobalt Blue and Alizarin Crimson make. For the black I mixed Ultramarine Blue and Raw Umber. This will most likely be put up for sale in the next group art sale – hopefully we can start those again soon.
