I came home with three new colors. The brits are always saying throw some raw sienna in the sky. Mine looks like an orangey brown, theirs looks positively yellow. The good news is that it mixes with cobalt or ultramarine to a warm browny grey.
This shows mixing the three new colors: rhodolite genuine, aureolin (cobalt yellow) and raw sienna with cobalt and ultramarine blue, alizarin crimson etc. Get an eyeful of that pink!
