Limited palette color mixing study

A couple of months ago I purchased one of Barbara Jaenicke's excellent monthly lessons that was about color mixing for oils. It also included color palette selection for soft pastels which was great because I could see her thought process on both mediums as well as a demo from start to finish to see how her process differs between oils and pastels.

Purchasing the lesson includes an opportunity to submit a painting to her for personalized feedback. And I was really impressed with the thought and care she put into her comments about the painting I completed for the lesson! It was very thorough and covered things I did well, plus areas to improve. She obviously put a good amount of consideration into her remarks which I totally appreciated.

After getting this feedback, I did another version of the painting, both to incorporate her notes and to continue practicing my study of chroma. I've been learning a lot about how to control the saturation of colors better, and in my initial painting the colors were much heavier feeling than I wanted. Barbara helped me see that balancing the local colors of elements with the effect of sunlight on them, as well as adjusting chroma, would help bring more luminosity to the painting.

For this study, instead of a split primary style palette I used a limited palette of double complementary pairs (orange/blue, yellow-green/red-violet), along with cadmium yellow light for lightening the sap green and adding more of the sunlight effect:
  • transparent earth red
  • ultramarine blue
  • sap green
  • quinacridone violet
  • cadmium yellow light

I toned the canvas with mix of ultramarine blue and transparent earth red, and did a monochromatic underpainting with these same colors. I like that the neutral mixed from these colors allows me to have a value roadmap without overly influencing the color temperature. Lately I'm preferring something closer to a warm grey over cool violets or red-orange tones.

I painted this same scene as a mini color study for day 24 of my 30 Days of Value Thumbnails project. So it's fun to see how my interpretation of it changes as I learn and explore. By doing multiple studies of the same subject, it's helping me see how the color temperature influences the quality of the light. For example, when I pulled back all the way on the warm reds and oranges (in the almost-finished stage below), it looked like a totally different time of day — more like mid-day instead of evening. Adding more warmth to the tree and adjusting the cast shadow made a huge difference.

Another thing I tried this time was to stop looking at the reference photo for the final 15% or so. I looked instead to see what the painting needed to make it feel right to me instead of just trying to imitate the photo. Which isn't accurate color information anyway.

I enjoyed using this palette, and I do think it helped with color harmony. I especially like that I was able to gain some control over chroma with it!
