Working on a Cassatt-style study, to explore the pigments she used and color theory ideas from the 1870s. (This is a demonstration for a class I'm teaching... but I like it and might develop it into a full-size finished oil painting)

where cool and warm light overlaps, you'd think they would neutral out. But cool light favors short wavelengths, and warm light favors long wavelengths. So, when you add them, you get a spectrum with a dip in the middle. magenta! so I painted a pale pink!

WIP, oil on 8" × 8" panel. Still life starring some random vessels from the thrift store. Lit with cool light from the left and warm light from the right. #oilpainting #oiloncanvas #art #painting

Another study of potato and garlic, this time with a warm light source. 8" × 8" oil on panel

Did this sketch in oils; session was about three hours. While I've been painting for 30 years, I've only just started my plein air journey - any #pleinair #oilpainting folks have advice on process or materials?

Big blue underpainting is finally done. Gotta let this puppy cure for a bit. Oil on 24" x 30" wood panel. #oilpainting

Small self-portrait study in acrylic. An attempt to demonstrate the effect of subtractive mixing: the cyan filter subtracts long wavelengths, altering the hue and saturation of the other colors in a predictable pattern. Did this as a demo for my color theory class with @drawingamerica.bsky.social

If the purple were duller, it would push the ochre more toward vivid yellow. Making the purple vivid changes the angle of "push" towards lime green. And yeah, these paintings were partially inspired by Kitaoka's bowl of gray strawberries :)

Some experiments in acrylic. The top one asks, "can yellow ochre read as red?" The lower one asks, "can yellow ochre read as green?" The top feels more successful than the bottom.

Trying put a blue underpainting, inspired by Maxfield Parrish's process. #art #oilpainting

Progress on "Self Portrait as Shadow on Snow." I snuck like so many colors into the "white" of the snow hehehe

A palette exercise. Painted this clavulinopsis auranticocinnabarina using only viridian, cad orange, Mars violet, and white. I could have gotten the shadows deeper. I decided to shift the hue of the greens to retain chroma - pushing the coolness, as well as the contrast against the fungus. #painting

Progress. Now those "dark" spots on the hillside are white snow in shadow! Next I gotta get the foreground trees under control. I'm thinking gold-ochre.
