Turns out you can't mix the right color from the wrong colors no matter how hard you try. Painting in progress of 102 Diamond mustard w/ veils. Yep, using a Bill & Jill auction photo for reference. Do I need permision, or to pay some fee if I bought the catalogue? ? -And the insulsulator? ? ( at the time, I paid an absurd amount for the insulator, three years later it seems like a bargain!) Seems like it'd fall under the parody guidelines at this point. Anyways, same yellow, ( cadmium) and a different green ( olive) finally got me past the hump.
