If you want to add atmospheric or emotional punch to your work, then squeeze some transparent Perylene Green onto your palette. It exhibits an almost black mass tone that spreads to a beautiful blue/green wash without producing mud - a color perfect for delineating shadows or creating moody landscapes, ominous horizons and stormy seas. A medium-staining pigment with intensity and softness, Perylene Green is highly soluble and easy to use. It glazes under or over other colors -"a very cool color," allowed one of our more demanding artist/testers.
