Working with Water¶
When painting with a wet medium (watercolor, acrylic and ink pen) you can set the amount of water to be used. With more water, the color will spread faster on the layer and wet colors are mixed.
Not only colors can be wet, with a 'Wet the Layer' button
(in the Layers Panel) you can wet the
whole layer. How the painting is blended and dried depends on the water
and the wetness of the canvas underneath it.
To wet only the painted parts of the layer, choose the 'Wet All
Visible' button
(in the Layers Panel).
To see whether or where a painting is wet, click on the 'Show Wet'
button 
. A light blue color shows the wetness of
the canvas and color - the more water is applied, the darker the blue
color will be shown.
To speed up your painting process we implemented 2 functions:
'Dry the layer' button
completely dries the active layer with
all its contents - painting, canvas and water applied.
You can use a 'Fast Dry' button
when you want the water to be removed
from your active layer but you want to keep the canvas wet.
Tip
Pause the fluid simulation anytime during painting by clicking the 'Pause Diffusion' button in the Layers panel 
. When diffusion is paused, the button is highlighted.
You can use different painting techniques to get various effects. In the following picture, you'll see how different combinations interact with each other. The wetter the canvas and color, the more color runs. However, dry tools (pastel, pencil, marker and airbrush) don't diffuse on less wet paint; they diffuse according to how wet your painting is:
