Daniel Lergon features works from the years 2015 to 2018 in his book, 'Unter Grün'. All were painted with the same kind of oil pigment known as phthalocyanine green. Sometimes appearing against a white ground, and other times, against a neon yellow ground, the pigment comes in a wide spectrum of tones, from a strange, bright, bilious green to a velvety black. These can be seen in Unter Grün, thanks to the artist's practice of applying paint in different densities, which reveals the multiple possibilities of this green. Each of the 'undergrounds' has a strong, very different influence upon the ambiguity that oscillates between painterly gesture and fragmentary figuration.
