Do purple and orange mix together well? Don’t they make mud? Why would I mix or layer these two colors?
Living in the land of red rocks – the Garden of the Gods – and awe striking outcroppings all over the region, I feel challenged to paint these marvels. They shoot up out of the ground showing off their shapes, shadows, colors and size, tantalizing us all. It is almost a Grand Canyon in reverse.
So how do we artists paint these rocks with the beauty that they deserve? The terra cotta reds and oranges are more of a challenge to mix and convey versus the greens of trees or blues of the sky, and then there are the cast shadows to capture.
As most of us know, orange and purple are secondaries on the color wheel – the primaries of red and yellow make orange, and the primaries blue and red make purple, but most artists do not know that orange and purple mix into a lovely burnt sienna. When I started to paint “Ascend,” I did not want to use the more typical blue for my shadows because blue greys the orange and makes the orange dull versus vibrant.
This second image (step 1) shows the first layer of paint, or underpainting, for “Ascend.” It was a warm, sunny afternoon, with the sun light coming from the right and fairly high. My sunny skies are always underpainted with a warm color – yellow, salmon or pink – and the sun is slightly cooler when it is mid-day, so I used a pale yellow.
Notice that the shadow shapes are either a cool blue purple or a warm red purple. The darker valued shadows are painted using a blue purple. All of the sunlight shapes are either yellow or orange.
A detour for a moment: I had never painted a tall rock from this perspective and I wanted to take on that challenge as well. It was important that the drawing accurately convey that the viewer is looking up into the sky.
Here (step 2) you can see that I have started to paint using local colors; I have gradated the sky and started to paint the rocks. In the shadows in the lower part of the outcropping, I have added a blue purple. The dark blue purple shadow color in the higher part of the rock are layered with orange. Notice the rich burnt sienna-like colors I get. To me, this is more appealing than using an ultramarine blue. And if you look real close, you can see that I added a ‘hat’ to the outcropping because I wanted the outcropping to project further up into the sky.
Would you have stopped painting at this point? Some artists might have.
At this stage (step 3) of the painting, I am beginning to model the rock, define the cast shadows and deciding how I am going to paint the highlights.
This composition is a bit tricky because my focal area is top of the outcropping where the warmest colors are. How to I give the viewer the feeling that it is very high up in the sky and yet use warm orange which tends to make the subject come forward in a painting?
Another challenge is that this outcropping has two ‘layers’ of colors. The top third is orange while the lower two-thirds is a white sand.
I decided to darken the sky (step 4) and make the gradation of it more dramatic; this I believe helps to give the feeling that you are looking up. The darker sky is also more purple, though it is not evident in this digital image, which harmonizes the colors in painting.
Some aqua blues are added to the white areas in the lower part of the outcropping. Again, this is for color harmony.
Also, I am having to take notice of the lines my shadows and rock shapes are making; their direction assists in the perspective I want to achieve. The white part of the outcropping is forcing me to use several light valued colors, which is fun to do.
Does this painting need clouds? I am not sure. There were wispy clouds that day.
To finish the painting (step 5), I softened many of the edges, particularly the left side of the outcropping and the lower right. Why? Because I want you to focus most of your attention to the upper part of the rock.
What do you think of the clouds? My local critic – my hubby – thought the painting needed clouds. What do you think they add or do they detract?
For a little more color and drama, I added a line of light orange on the edge of the shadows; this is the first time I have tried this technique. You can see that the highlighted edges of the upper part of the outcropping are more yellow, whereas I allowed more pure whites in the middle.
There is not an ounce of ultramarine or cobalt blue anywhere in the outcropping. Have I convinced you to try out your purples with orange subjects?

2. The middle rectangle color of orange was then applied. I made sure it was the same value (same darkness) of the outlining red.
4. Again, with a palette knife, I began applying the darkest darks that were to be in the painting. I am primarily using the edge of the palette knife to get this effect.
5. At this point, I noticed that I had been leaving the middle of the painting alone – as if I had two paintings going on at the same time. Eventually, I figured out how to bridge the gap. The winding dark brown strand on the right is reminding me of a spinal chord for some reason. Executing how to capture an inner glow and conveying layers is still not quite clear to me.
6. Finally, I just dove in with a brush and began interweaving lines on top of the previous layers of paint. You can see the lime green has been added and I have also begun to articulate some geometric squares. At this stage, I go back and forth between a palette knife and brushes. The left side edge of the painting is bugging me – where the whites meet the red – and I am not sure what to do. I am liking the painting and I am now afraid I am going to ruin it. Life as an artist does cause us to shake in our boots.
7. I printed the previous image (step 6) off of my printer and sketched in the parallel lines you see on the left here in step 7. The composition of the painting needed a few more obvious geometric forms. Note the 3 small rectangles to the center right. Small organic shapes have been painted with white, allowed to dry, then I calmed the white down with appropriate tones and colors.
