Watercolor, 35 x 26 cm. Paper: Fabriano artistico CP 300g.
This is a couple of Silver washed fritillary in a forest meadow in Lisbjerg Forest near Aarhus.
It's watercolor, but I used a couple of nearly opaque watercolors for ligthening several areas: Turners Yellow and Naples Yellow Deep. These are both single pigment colors and they're both Winsor Newton). They behave nearly as gouache, but they are much easier to use as they come in pans and don't dry up.
