Why paint over a transparent wash?

In this video Dutch painter Janhendrik Dolsma gives you 4 reasons to paint over a transparent wash:
1. It has a unifying effect
2. the possibility of applying highlights in the wet wash
3. the color of the wash sets the tone of the painting
4. colors blend in easily

Dolsma explains the process while working on his Evening Clouds painting.

Dolsma participated in exhibitions in the Netherlands, Germany, the UK, Taiwan, Spain, Belgium and the USA.

I've been underpainting washes for a few years now, even in my murals. It's improved my work, I think. Well done and good insight!

A vibrant orange, red or yellow directly next to an almost pure white highlight can create a very "hot" glow, which the warm underpainting is very helpful with. Additionally, a saturated warm color along the edge of an object with a bright backlight (where we see only the shadowed side of the object) can create this same glowy feeling. Alternatively, if you want to paint a scene with a cold main light source, it can be useful to start with a blue, purple or green underpainting.

This painting is stunning. I did my first ocean plein air painting a couple weeks ago, I’ll be taking this advice with me when I go back.

That is a clever way of getting an orange glow consistent throughout the painting. Nice painting, impressive.

[GoreTheSummoner]

it turned out beautiful. the touch of whitewash on the bottom left foreground does a lot of work. looks great.
