Watercolor tutorial How to paint Glass
1. Set a glass on a table, as seen below. The photo shows you how the glass is set up. But I am not going to paint the glass from the photo. Notice when the background is very light, the glass appears darker than the background. If the background is very dark, the glass would appear lighter than the background, because of the reflection from the glass.
2. Do a very light pencil outline on the watercolor paper. Then use the masking fluid to protect the high lights. Notice that my angle of the veiw is a little different from the angle of the camera's view.
3. Use a #18 brush, mixing the background color with yellow, a little bit blue and a little bit purple. It's better to not use grainy pigments in the early stage to avoid your painting from getting muddy after you painted several layers. But, it doesn't matter if you use good quality paper.
4. Use a #12 brush, to put down the middle tone colors you see in the rest, looking carefully to find the blue greys, yellow greys and purple greys. Avoid putting the same color all over. Then take all the masking fluid off using your fingertip.
5. Use a very light warm color, yellow with touch of red, to paint all over the glass.
6. Mix light greys to paint the greys that you see in the glass. Mostly appears on the sides of the glass, to make the glass darker than the background. Then paint the edge of the white board and the edge of the yellow paper.
7. Using a very small brush, carefully paint the lines you see in the glass, so that the glass will look hard surfaced.
8. Paint the shadow of the glass. The shadow is mostly blue greys, but there are also warm colors in the shadow, which come from the light penetrating through the glass.
9. Use a clean brush to lift the highlights that have been lost during the painting process. Or you may use opaque whites to get the highlights back. DONE!
