簡明的色塊、完美的弧狀、充滿生命感的類幾何圖像，是劉永仁賦予作品最鮮明的形象，他將自然甚至宇宙的一切形象剝離僅剩線條與塊面，觀者可以想像畫面中出現山坡、河流、小屋、星星抑或天際線等，而這些抽象化的自然痕跡，是宇宙萬物的象徵，也是劉永仁跨越自然與精神界的造形方式，他曾提到：「我著迷的形，通常是融化表象之後浮現的異形，那是表形之內真正的內在形，也是拆卸知性功能之後，進入潛意識之內的形」。
Concise color blocks, perfect arcs, and lively geometric patterns compose Liú’s abstract paintings, establishing a distinctive visual language. These small, repeated arcs and curved line signify the abstraction of images from nature, suggesting actual physical objects such as hills, sheaves of grain, rivers, sails, windmills, the horizon line or stars. Yet these geometric forms are not meant to represent physical objects, but rather symbolize the myriad things of the universe, which also shows viewers an interface where the natural and spiritual realms can alternate. During an interview, Liú once said, “I want to create ambiguous forms, like semi-abstract shapes that are between abstract and figurative. My intention is to find a way to create forms that are beyond the geometrical dimension.”
