CIE L*a*b* 색 이론과 색채심리에 기반한 장르별 디지털 앨범 자켓 색채 특징 연구

초록

This study addresses the lack of research on how digital album cover colors influence genre characteristics and audience psychology. As digital albums have become a major medium for music consumption, color functions as a key visual cue, yet its structural and psychological effects remain underexplored. Based on the CIE L*a*b* color space and color psychology, twenty Billboard-listed digital album covers representing Classical, Pop, Jazz, and Hip-hop were analyzed. Using Python-based automated scripts and K-Means clustering, dominant and auxiliary colors were quantified through L*a*b* values and ΔE. The results show that each genre displays distinct chromatic patterns-low-lightness orange-brown and violet in Classical, high-lightness warm hues in Pop, mediumto- low-lightness cool tones in Jazz, and high-contrast low-lightness backgrounds with bright accents in Hip-hop. An SOR-based survey with 153 participants (September 12–20, 2025) confirmed that these color features significantly affect psychological orientations and genre judgments, yielding a 36.93% classification accuracy. The findings demonstrate that digital album cover colors are structurally genre-specific and influence audience perception, offering theoretical and practical implications for visual design, branding, and color-based recommendation systems.
