            Especially when employed in the "modeling" of faces
            and bodies, shading lent a realism where it was needed
            most: on the sacred figures at the center of the icon.


             Main Shading Techniques

            The painters of Tibet used several techniques for shading
            and colour gradations, but most of them can be typed as
            either "wet" or "dry" techniques. "Wet shading"
             (rZon mdangs), the blending of two wet colours on the
             painting surface, was employed for the most part only
             during the laying on of the initial coats of colour. "Dry
             shading" (skam mdangs), on the other hand, was usually
             a secondary step. It consisted of the application of
             successive thin washes of colour over a dry preliminary  byug mdangs       'bru mdangs
             coat. Both dry and wet techniques in their simplest
                                                              ("spread-on shading")   ("granular shading")
             forms have been described in Chapter 8 in connection
             with the painting of the sky.
                 Wet shading, as we have seen, usually required
             more than one brush. The colour at each end of the
             gradation needed -its own brush, and often a third was
             used for the intermediate hue. Dry shading, conversely,
             was executed with only one brush, although this in no
             way prevented the artist from achieving a variety of
             shading effeCts by altering the size, shape, direction and
             frequency of the brush strokes. For the painting of skies
             alone the Bhutanese painter Kunsang Tobgye actually
             enumerated as many as four types of dry shading:

             I)  byug mdangs ("spread-on shading"): the usual
                 evenly graduated dry-shading method. According
                  to the artist this method was most appropriate for  sprin mdangs     char mdangs
                 shading the skies in paintings that depicted peace-
                                                              ("cloud shading")       ("rain shading")
                 ful (zhi ba) deities.
             2)   'bru mdangs ("granular shading"): shading with
                 .small dabs or dots of indigo, applied thickly and
                 close together at the zenith, but less frequently  Four different types of dry shading.
