My goal is always for my subject to stand out from my background. I usually try to achieve this by making the background darker so the subject appears lighter and making the background cooler and the subject warmer, which I usually do by adding layers of blues over the background and yellows and oranges over the subject.
I thought I’d try something different with my current painting, though. Since my subject is a bird with blue feathers, I knew painting yellow over him was out. That would just turn him green. Painting orange wasn’t much better because that would dull him and send him further into the background, exactly what I don't want.
I remembered what I’d learned from Alicia Farris’s watercolor workshop and that's that layering analogous colors, or colors that are near each other on the color wheel, makes shades more vibrant. I could certainly use some more vibrancy in my subject. That would probably be a more effective way if getting him to stand out than trying to "warm" him. I chose cyan blue to layer over him. I could've chosen any blue, as well as purple or green. With just one layer of the cyan, he started to come forward more. On the other hand, his neck is more of a warm brown, so I've been painted red over it to get it to stand out more.
I've added more layers of blue to my bird since I started writing this post. I'm looking at the painting now and he's standing out nicely from the background. What I think I need to do now, though, is create more separation between his feathers.
