Lasso Fill

 Lasso Fill

The region you define with the lasso will dynamically fill with the active color. It is useful for blocking out silhouette shapes and a powerful addition to coloring workflows. 

For more control, use smaller lasso regions to consecutively build up to your final shape.

Lasso Fill can also be used with Randomize Color and Transparent Color.

Lasso Fill can be found in the Fill sub-toolbar.
