1989年生於臺北，2018年畢業於國立臺北藝術大學美術學系碩士。他的創作聚焦於個體面對社會規範與期待時的掙扎與真實感受，並以繪畫的口吻回應身處其中的無力感。蔡瑞恒以濕潤、透明與混濁的質感創造畫面，筆觸隨意而不羈，顏料之間的不完全融合揭示出層層情緒波動。這些畫面充滿滑稽與混亂感，描繪生命中的迷茫與矛盾，探索個體在矛盾社會中的掙扎。儘管筆觸奔放，畫面中仍隱含結構性的重組，藉此回應現實的荒謬與無序。蔡瑞恒的作品如同生命中的亂流，揭示人性深處的失落與希望，並以鮮明的視覺語言挑戰社會框架。
Cai Ruei-Heng was born in 1989 in Taipei, Taiwan. He has an Master's degree in Fine Arts from Taipei National University of the Arts, and a B.B.A. in Industrial Management from National Formosa University. Cai Ruei-Heng's paintings investigate the fragmentation of our world and the accompanying sense of powerlessness. His practice reorganizes and reconstructs the ruins of this disintegration to create a new visual language that mirrors the confusion and chaos of modern existence. Employing an eclectic and subversive painterly approach that combines abstraction and figuration, Cai Ruei-Heng challenges traditional concepts of stability and order. He attempts to reassemble and respond to the disintegration of reality in a distinctive painting tone, often presenting chaos and a sense of absurdity that reflects people's confusion and bewilderment towards life.
