Denise is well-known for her love of sap green, but in curating her new Earth Friendly Da Vinci Watercolor Pan Set, she was striving to create a version that avoided the use of nickel azo yellow while still having a warm, earthy glow. This new blend can be straight from the tube as a convincing natural green, adding indanthrene blue or green gold to deepen or lighten the mixture respectively, but it also cooperates well with other colors. It creates a wide range of rich browns when mixed with reds, moody teals when mixed with deep blues, and even a beautiful turquoise when mixed with cerulean blue hue.
