'Into the Twilight' 18 x24 pastel with oil underpainting
I love the versatility of pastels. There are so many ways to start a painting and one of my favorite ways is to start with oil paint. I do some kind of underpainting for probably 95% of my paintings. I find the painting process more exciting with an underpainting, especially the wet drippy ones. I recently posted a watercolor underpainting demo and starting with oils is similar but the results are most definitely different!

I find that the oil paint underpaintings are richer and more intense than watercolor. I also prefer the results when the paint runs and drips. With the oils, the turpenoid creates the greatest drips that look like spiderwebs or roots or nerve endings. I love them! They are perfect for marsh grasses and meadows filled with grasses. Here is what you need to do this technique:
- You need a surface that can take a solvent based underpainting. I prefer UArt pastel paper.
- Be sure to use an inexpensive bristle brush, The sanded papers will ruin your brushes so you don't want to use your good ones.
- I use regular oil paints and thin them with turpenoid. You want the paint to be thin...the consistency of tea. If it is too thick it will fill the tooth of the paper and will take too long to dry. The thin paint should take less than an hour or so to dry.
- You have to experiment with the consistency. If it is too thin and drippy than you won't get good spiderwebs. I like to put down my darks first and then let the other colors drip into the darks (see photo)
Demo of Twilight Marsh pastel
- (from top left) Finished underpainting on Uart 18x24. Lots of great drips!
- Close-up of my spider webs in the trees.
- Terry Ludwig Pastels Sunset set. I used some of these wonderful colors for the sky.
- Starting the pastel by blocking in the darks. I like to keep them the same value as the underpainting.
- Starting the sky. Putting in some blue purples and yellows. I add some reds and oranges to the tree line so they will look like they are catching the light of the setting sun.
- Adding more dark purples to the sky. I decided I want the scene to be closer to twilight after the sun has set.
- Now I blend the sky. I don't want the sky to be too busy and compete with the marsh grasses.
