This study aims to examine how perceptual responses formed through the observation of natural light and changes in the sky are expressed through color in painting. As a practice-based study focusing on color expression in the creative process, it explores how natural light encountered in everyday life is perceived and transformed into perceptual impressions, centering on the author’s painting practice. The study is based on a literature review grounded in Maurice Merleau-Ponty’s phenomenology of perception and Rudolf Steiner’s theory of color. Based on this theoretical framework, the works were analyzed by period to identify tendencies in color application and the characteristics of pictorial image formation. The analysis reveals a correlation in which changes in environment and modes of perception lead to differences in color usage and corresponding formative transformations within the pictorial structure. In this process, color functions as a primary formative element that organizes and conveys impressions of light. This study is significant in expanding the formative and expressive possibilities ofcolor in the representation of light and in extending methodological approaches for organizing the impression of light through color within practice-based painting research.
