123 Tree! Demo

                  Detail of a painting from 2010
There, a eucalyptus tree. Well, the way I like to paint them right now anyway which is not to say you can't paint them any other way. I'm still evolving with my trees with each painting too. This demo I took from a painting done in 2010, and sold to a good friend here in the valley, shows basically a 3 step process I use quite often for trees.

Step One....the basic tree shape is blocked in with the dark shadowed colors. I like to use a mix of ultramarine blue, alizarin crimson and just a slight bit of cad yellow light or pale. for this reddish dark color it would be like UB 40%, AC 55% and CY 5%.  I always throw in a bit of cad yellow. The more cad yellow you add the greener it becomes.  Try to paint the darks of the tree as thin as possible so the paint can tack up some. If you are working alla prima then try and paint just the areas where the darks will be seen and leave other areas for the lighter colors.

Step Two....you can do this 2 ways. Add a lot more cad yellow to make a lighter mid value green out of your dark mix or just mix up a new batch of mid value greens. I do it both ways. If I am adding to my dark mix I try and save some of the dark mix for later touch ups if needed. Work from the top down and let the dark colors blend into the mid value mix. This fades the light colors into the lower areas of the tree and the shadowed side of the tree.

Step Three....either add more cad yellow to your mix or mix up a brighter yellow/green for your highlights. This is added just where the sun is really hitting the tree. I like to add some yellow ochre too in spots. Yellow ochre gives you that great olive drab color which is perfect for oaks and eucalytpus trees.
 Lastly, I add the trunks using pinkish whites, greys, tans or even light pale blues. At the tops of the trunks I add a little more ultramarine blue to give them shadows as they disappear under the foliage. Gives the trunks a nice realistic look and sense of tree shape....branches causing shadows. Also, add skyholes. Trees are rarely solid masses except in the distant background trees and at times they even have some skyholes. I always save some of my sky colors just for this purpose. Shape your skyholes to line up with some of the trunks to make the trunks believable. Actually, you are creating shadowed trunks and branches with the skyholes. Just imagine the trunk or branch shape and paint one side of the skyhole and then the other leaving the dark trunk or branch in between them. What then appears as trunks or branches are actually just your darks of the tree that you painted in Step One. It's all an illusion that makes sense once the painting is finished.

There are many ways to paint trees. There are many color palettes and paint combinations you can use. A popular one to use is blue or even dark green shadows....cool colors. I've done those too if I'm not using a warm color like my dark red here. They say there are no rules in art right so you could use any color you wanted as long as it is dark....I tend to use the reds, blues and greens depending on my overall palette of the painting. My foreground grasses in this painting were warm ochres so I went with warm shadows. Had the grasses been spring or winter greens I'd go with cooler shadows like green or blues. This is in keeping with the color harmony working in a painting. Whatever dark you use make sure your other colors have just a hint of it in them to work the color harmony.  Dark grey shadows...mix grey greens for mid values and lighters greys to your highlights....it's possible, anything is possible when you paint.

Trees can be overwhelming they are just so complex and finding a means to suggest them simply is always difficult. You have really captured the character of the eucalyptus tree which is really what we are after as landscape painters, the personality of nature, and to imply and suggest form without laboring is just not a easy task. Thanks for a great demo I am always interested in to approach trees.

Thanks Jim. This 3 step method works pretty well for me. I've used it to paint more open trees too like sycamores and elm type trees and it works well with those. Trees seem to be more work to learn to paint and I'm still very much learning them as I go along. Thanks again.

I just found the comment you left on my blog... I am seriously impressed with your work and talent Ron. It is so obvious when an artist has had training and years of practice and experience. I envy you that. I only began painting about a year ago and struggle sometime to achieve what I want... It is good to have art in my life.

Hi Dennis,
Thanks for the good words. Your rt is coming along just fine. We all go through that learning curve, every one of us. Persistence makes us all better. Sometimes what we see in our minds can take some time to create on the palette as our talent has yet to catch up. It can be frustrating but eventually we gain that needed talent and things begin to happen. Hang in there Dennis, it will happen for you.
