Here's a view of Mueller Lake Park in my neighborhood painted in the "Full-spectrum Triad" of colors. All colors made only from 3 colors. I've been rereading Dory Kanter's book on journaling where she suggests trying these different triads for different moods. I painted this first, then went back and added outlines in pen.
I'm also beginning an online mini-course on journaling through Cathy Johnson. I love her demos so I posted one here. Not one from the course because those are currently not public, but another that has been made public.
