Value vs. Color in an Acrylic Painting
One of the trickiest things about acrylic portrait painting, especially when using the glazing technique, is knowing how to achieve color. How many layers do you use?
I’ve said it before, and I’ll say it again. There is something more important than color, even skin tones in a portrait.
Here is a recent question from a subscriber:
Currently, I am working on a portrait of my friend’s grandfather. My reference photo is of him as a young man in his dress greens from his younger days in the Army. I really want to capture his likeness and be proud to present this to her as it is a gift for her mother but I’m finding myself “stuck” in a sense. From watching your videos and using the matte medium as a glazing technique, I am having trouble building up the layers of his uniform to the correct tone and shade of green. I find the medium lightens the acrylic paint. I’ve only applied one layer so I still have time to correct it before making a mess of it. Should I have painted in the dark value of his uniform before going in with a glaze to help it along or just keep applying layer after layer until the desired color is achieved?
Regarding your question–yes, you can keep building up the green glazes for his uniform. However, it’s best to think of values before color. What I mean is, you are right to think that you should have done the dark value of the uniform first. That’s exactly right.
The reason is, value is more important than color. Value (light and dark and the difference between them) describes all the contours and three dimensions of a face or body. If it weren’t for the strategic placement of those values, we wouldn’t know whether it was a person, animal, rock or tree that we painted.
Theoretically, you could have a person whose skin tone or clothing was a bit too red, or greenish–whatever–but it the values were accurate, it would still look human, and would look like a pretty good portrait. You can see in this painting I did, the colors are a bit too red. (I also intensified them on Photoshop, exaggerating them a bit to make a point.)

But flip that around: make the skin tone or coloring right on, and the values completely off, and you will have a terrible portrait.
So, when I instruct my students in painting, I teach them to see the value structure first. We start off simple, using one or two colors, and then add as we go along. Much more important is seeing the overall lighting in the portrait–where the light source is, the darkest values (whether clothing, hair or just deep shadows, it makes no difference) and the mid-tones and capturing them faithfully. Of course, this assumes that you have the form correct. That is, that the proportions of the face and anatomy are accurate.
So, is your painting ruined? No, not at all. Just keep building up layers. But it helps to build up the darkest values first. Don’t neglect them. Think of your painting as an old polaroid photo. The print shoots out of the camera and fades in slowly, all together. You don’t get eyes, then hair, then a mouth, then the body. No. You get everything at once, but it’s all light. Then, in about 30 seconds, you have a print.
(Wow! Imagine that. I’m old enough to remember how cool it was to have an instant photo before digital cameras.) 🙂
So, you want to paint your painting like a polaroid. All at once, just fade everything in. As much as possible. That means that you hit those dark values first, and then work your way into the lighter ones.
As an example, let me show you this. Here is an image of how I did “Smoldering Wick,” an acrylic portrait illustrating a time when I struggled, and found encouragement in the scriptures.
All of these many layers is how you make an acrylic look like an oil. I learned this glazing technique several years ago from Norbert Kox, a university art professor. It made all the difference for me in my portrait painting with acrylic. Learning this technique and applying it will make the difference for you too.
