This is one of my favorite motifs and color combinations. To be honest, I’ve painted it 3 times. Once in watercolors and twice in oil paint. I’ll probably do it again. Just because!
The darker grey blue is a mix of Vasari Transparent Brown Oxide, Gamblin Indanthrone Blue and either Gamblin Warm White or Titanium Zinc White. The coolest thing about it is that the color will change slightly – show more of the brown oxide – the more I work the paint into the paper.
