Gouache Underpainting, the Final Chapter
I admit to being a complete newbie when it comes to 1) painting 2) color and 3) portraits. So I really didn't know what I was doing. I chose some colors that I thought would make a good skin tone, and mixed them willy-nilly. I ended up with a color that would look good on a tropical parakeet... but I wasn't going to throw out all that paint. So forgive the ultra-tanned sheen that makes Grandpa look like he's a snorkel instructor in Tuvalu.
I attempted to paint over Left Grandpa. I mixed four values with this shade, but added some blue into the darks for a more interesting contrast. I mixed a few shades of suit and hair color as well. And I painted over.
I forgot to paint the glasses. Anyway, You can see that on the face, the underpainting didn't show through at all. I used opaque mixes for the face, and although the underpainting was a good guide, it didn't do much else. It was great to paint on something other than white, though. On the suit, I used a much more transparent mix, and the underpainting showed through.
Here are some of the techniques I used. You can see the results - not too great. Dry brush looks terrible. Add water and it gives nice texture. Scrubbing an area lifts like nobody's business.So I learned how to make it work, but didn't much like the results. Lesson: if you make the second layer transparent enough for the underpainting to show through, it tends to lift. Therefore, my actual painting of grandpa will use a watery wash as the underpainting, so I am not painting on white. From this experiment, mostly I learned what not to do.
