I wasn’t expecting to see such a variety of pigments used. One can only imagine what they looked like fresh and new thousands of years ago. Some of the pigment was applied by hand and other sections were blown from the artist's mouth, or perhaps a reed, resulting in a spatter pattern. You can also see that, in addition to being painted, some figures also have sections that are incised into the rock. Sadly, there are also numerous bullet holes from the days before such artifacts were appreciated.
