Radiant Colors in Oil and Acrylic

Recently I discovered I enjoy working with both Galkyd Gel and Cold Wax Medium. The suggestion for Galkyd Gel was by Dave, one of the techs over at Gamblin, and I have been enjoying it as an impasto medium quite a bit. The cold wax is also excellent for building texture and a really beautiful matte finish.

I started a long landscape to try these mediums out, and with how quickly Galkyd Gel dries (within a day or two), I was able to continue building layers over the course of just a few weeks. I’m not one much for slow dry painting, so Galkyd medium is usually my go to. I get enough blending time in to do what I need, then can come back within a day or two to continue progress.

This is the painting in its initial stages, before more texture and detail was added.


About two months ago, I was able to tour the Gamblin factory down in Portland. It was a wonderful experience, and I left with a huge smile on my face, as well as a sample of their Radiant Green. I wanted to apply the radiant green in a way I might not have thought of, so I used it for small details and highlighting as I continued my painting.


Radiant Green was used on the water as part of the reflections. I was loving it.


I premixed all of my colors on my palette, but didn't need to mix the Radiant Green. I let it do its thing. It was a really nice experience working with it and I was very content with the finished painting.



The complete work- 12"x36" oil on canvas, painted from a photo I took at Deception Pass.




Given that the colors were beautiful in oil, I decided to try them with acrylics and Golden's Open Matte medium, a slow drying medium.

8"x8" round canvas done in acrylic with Golden Open matte medium to slow dry time.

Golden's Open Acrylic line definitely delivers. I found that it blends similar to oils and stays wet for at least a half hour if you leave it alone, but much longer if you continue painting.

How I achieved this was with Golden's Open Acrylic Titanium White as a base layer. From there, I mixed in a little bit of Open Matte Medium with the acrylic colors I chose in a cheaper brand and started blending, doing a wet on wet technique.
Getting darks was a little bit more difficult with the acrylic over the slow dry titanium white, as compared to doing the same with oil paints in Bob Ross's style (I love Bob Ross).

I'll be trying a thin layer of the Open Matte Medium soon with another round canvas to see if better darks can be achieved.



Thanks for reading!
