The exhibition 400-700 Nanometers by Aphisit Sidsunthia delves into the imperfection and limitations of human perception. The title refers to the wavelength range of visible light, a narrow segment within the vast electromagnetic spectrum. Other familiar yet invisible wavelengths include X-rays, UV rays, microwaves, and radio waves. This limited perception underscores the inherent constraints of human understanding and existence. Through his monochromatic paintings, Aphisit reflects on these limitations, emphasizing ambiguity, imperfection, and the infinite nature of humanity.

By minimizing the use of color, Aphisit distances himself from conventional color theory, embracing the notion that some colors do not naturally exist in the light spectrum. Living with colorblindness, he incorporates his personal inability to perceive certain colors into his art. This monochromatic approach sharpens other visual elements, allowing for a deeper sensory engagement. Black and white imagery evokes an otherworldly dimension akin to the infinite darkness of space, a realm beyond human comprehension.

Shapes resembling voids in Aphisit’s works transcend emptiness, transforming into layered forms or dimensions. These layered elements reconstruct weights and depths, challenging the flatness typical of painting. In a world dominated by high-resolution visual culture, Aphisit slows down the rapid, often subconscious, process of perception. He invites viewers to embrace ambiguity and incompleteness, hallmarks of postmodern aesthetics.

Aphisit’s works encourage audiences to question what they see and perceive as truth, as well as humanity’s desire to fill its inherent voids. The concept of completeness, he suggests, is a fallacy. Identity and existence are fluid, infinite, and ever-changing, perpetually in a state of becoming.
