I spent the afternoon producing an alternative to the Zorn palette. I wanted to try two things: a new paint brand (Langridge) and a slightly earthier selection of pigments: Gold Oxide (more yellow/richer than Yellow Ochre), Red Oxide (a brick red, quite stiff, with a very high tinting strength), Payne's Grey (my blue black) and Titanium White.
I think the result is pretty harmonious.
Some very subtle pinks and greens.
In each 'puddle' of colour I added a pea size blob of Galkyd to speed drying.
The canvas board is 20"x16" (50x40cm).
I followed Michael Lynn Adams' steps to complete the chart, and it took around 3 hours from start to finish.
