The large-scale rubbing 'All I See Are Light Patterns' continues the artist's long use of his “frottage” technique, in which the canvas is placed on a cardboard plate, which is then rubbed with an oil stick to transfer an image. The 2021 painting depicts the forms of the artist’s usually recognizable world dissolving, and in grayscale, introducing a dystopian element into his world cosmology.

These coloured light panels which Mullican began in the 1970s already, concern themselves with abstract re-drawings of figurative scenes, reducing them to mere outlines. This graphic abstraction by means of reduction also recalls Gerhard Richter's coloured chart pictures from that time.
