This is a little color study of my 2017 garden's first tomato. It's not ripe yet, or at least when I shot the reference photo, but now eaten. Very tasty. I'm trying to finalize a simple palette based on Denham Ross's efforts to sort it all out. There is a book called The Painters Pallete, A Theory of Tone Relations, an Instrument of Expression. Published by Forgotten Books available on Amazon for about $10.
I've been 'studying' this for a while using a google pdf. My friend Judith Reeve uses variation of Ross's palettes to paint some very extraordinary work. My interest is the tonal harmony.
It's not a complete spectral color wheel, missing an orange, the red orange will do. The colors are all derived from standard tube colors, Lukas 1862, A key ingredient is Indian Red for making my red and the three 'purples'. Great for correct compliment neutrality. I hope the have the painting done by the end of the week or at least before we go to Maine.
