I started testing R&F Drawing Oils to see how they hold up over time — but the results were not as simple as “passed” or “failed.” Some colors changed after months of exposure, which led me to question whether the pigments were fading or if the surface itself was affecting the results. This is an ongoing test that I’ll continue updating.

I tested R&F Drawing Oils on watercolor paper, sketchbooks, and more—layering them with pencils, acrylic, and pastels. Here’s what worked, what didn’t, and how they dried over 2 days.
