This video demonstrates the "light version" of the masters technique in oil color glazing. That technique can also be applied with acrylics.
It basically starts with a black and white underpainting with colors glazed over it to render a colored piece.
This is not the whole OldMaster painting technique, more or less a "light" version of the process to get a feeling for color application by glazing.
