William Van Doren, IMPROVISED SOLAR COLOR WHEEL. Sunset from Stony Point, Albemarle County, Va. Oil on Arches, 17 x 23.
My sketch of this sunset included some improbable color notes for the area around the sun: “flat hot yellow gray (lilac) extends way out” and then “could be sepia + violet + (warm) white + yellow with optical bands of green.” (Meaning, I saw green every time I blinked.) And as the sun went down behind the mountains, there was deeper gold and violet.
