Opposite colors

These opposite colors mix to make a neutral dark. It seems like just yesterday I painted a painting with these colors as the major opposition. Perhaps not these pigments but close. I really don't like the Sap Green pigment, especially in watercolor, it's like Davies or Payne's Gray, too recognizable and too much Black pigment in them. This duel-tone lighter hue is easily matched with other pigments though.
