Accordingly, this study aims to analyze the fashion-related color images and color schemes depicted in Korean digital cultural content, using promotional Youtube videos produced by the Korea Tourism Organization promotional YouTube videos as the subject. The research methodology involved a literature review as well as referencing previous studies and monographs to examine the concept of K-fashion, the concept of color image scales, and the concept and components of the NCS. For the quantitative research, we collected videos, extracted adjective images associated with color schemes, and analyzed color and nuance areas. The study's findings are as follows: First, most color schemes were concentrated in the 'Hard' and 'Dynamic' zones.
