Watch artist Redd Walitzki use a variety of wet on dry watercolor techniques, and see her process for painting an eye and hair.
This is where the painting gets tighter and more precise. With this wet on dry (meaning the paper is dry where we are putting paint down), its all about slowly building up areas of color and details. I included a few annotations to give more insight into some of what I'm doing here. But mainly this just takes a lot of patience while you slowly refine the painting. Since you can't really blend in watercolor, I tend to build things up slowly, adding as I go. You can see me using a color blotting palette in some of the shots (I'm using it the rest of the time too, but its off-screen). That gives me a chance to see if my paint is light/dark enough before I put it down on the painting.
After I laid down the dark tones in the hair, I ended up revisiting the contrast in the face and eye to make it a little punchier to match the hair. If this watercolor was the final result, I would finish it off with some white & black liquid acrylic details (the bling on the eye & cheekbones for example). But for me, this is still the underpainting and I'll finish the piece out in oils, where I can blend more.
This whole process takes a long time, so if you're trying it don't get too frustrated & try to stay patient!
