The problem given was - select a blue, a yellow, and a red and then with each different study change your yellow. Minimizing my palette helped me organize my thoughts which were focused on value and temperature. I started with Yellow Ochre Pale, and then tried Cad. Yellow Medium, as well as Gamblin Transparent Earth Yellow.
I'm learning so much from experimenting with different minimal palettes. I can see my shortcoming in values and temperature much more readily so I think I'll continue doing more of these studies.
I'm leaving very chilly Chicago for the warm temps of the Southwest for a couple of weeks. Since it is my practise not to take a computer when off, I won't be blogging until later. Happy Art-making and viewing. Thank you for sharing your comments
