color palette

primary · titanium white · payne's gray · sap green

secondary · ultramarine blue · raw umber

Mix various shades of gray by combining white, Payne's gray, and small amounts of raw umber. Achieve the greenish hues by adding sap green to the gray mixtures. Use ultramarine blue for the sky and to cool down the mountain colors.
