In this video I swatch the Paul Rubens watercolor 12 half pan set and then put it straight into a real painting so you can see how it behaves beyond a quick dot card. I do swatches, move some paint around with water, and then paint a nature-journal style sketchbook page so you can judge the color range, how easily the pans re-wet, and what the washes look like when they dry. If you like seeing supplies used in an actual page (not just a chart), this one is for you. I also test-drive a few supporting tools for the setup: Arrtx washi masking tape to create clean sections, and the Paul Rubens 100% cotton hot press hardcover watercolor journal as the paper surface. I use my Tombow Mono waterproof drawing pens for the line work so the ink stays put when I paint over it. If you want more swatch photos and my ongoing brand evaluations, lightfast tests, and fugitive lists, I keep those organized on my website—and I also mention that I really like the color options in the larger Paul Rubens 48 pan set if you want more variety.
