Another day in the studio working on the underpainting. Played with a variety of blues, the turquoise, the ones that lean towards green and the warmer blues. Played with the values by adding bits of white to lighten, burnt umber to darken. Muted the blues with a bit of yellow ochre and added highlight oranges with Winsor yellow deep. Worked with a variety of bristles, sable, and fan brushes to vary the mark-making.
