This painting was painted using a palette that's used by the famous Dutch plein air painter Rene.
If you haven't checked out his blog please do, it's very inspirational. Almost every day he's painting the dutch landscape and cityscape.
Rene uses cad yellow light, kraplak (madder lake) or permanent alizarin, ultramarine blue dark and titanium white.
