Sun Pei-Mao was born in Taipei, Taiwan in 1991. He received a Masters in Fine Arts from the Taipei National University of the Arts in 2017. Over the course of his studies, he participated in an exchange program at the China Central Academy of Fine Arts in 2016. Sun Pei-Mao's painting practice is an explorative one. He creates a unique visual language that represents his experience a with mild color blindness which rendered him unable to distinguish most of the intermediate hues that other people can see. Nevertheless, this created in him a growing preoccupation with color exploration and experimentation. Precise in style, Sun Pei-Mao uses a variety of vibrant colors to create "film-like" figurative compositions comprised with strong oriental elements. This infuses his paintings with a singular quality of bizarre yet extraordinary visual conflict.

In 2019, Sun Pei-mao has been selected as one of the EACA Artists by Atria Foundations. His work has received numerous awards include a Superior Prize of Taipei Art Awards in 2017, a Second Prize of Painting by Taipei National University of Arts in 2012, and the First Prize of Bright Star Project in 2012.
