This is cotton stretched canvas, 16 x 20 in. gallery wrapped, and painted around the sides, ready for hanging.
Thickly painted with a palette knife using only 3 colors plus white. Yellow Oxide, French Ultramarine Blue, Magenta. The mixing of the paint on the canvas with a knife causes the color mixing to very visable rather than blended. You can see from the close ups if you click on the photo what I mean. Though the colors are bold, when mixed they become subtle but striking.
