The first "LOVE" paintings were red, blue and green because my father worked for Phillips 66 and in those days, in the 30s and 40s, all Phillips stations were red and green; the gas pumps, the uniforms, the oil cans. It was a large Phillips 66 sign against a blue sky which I passed hundreds of times as a boy which determined the colors of the "LOVE" painting.
