Color has become a fundamental element in contemporary visual arts, significantly influencing emotional resonance and narrative depth. Alberto Mielgo, an acclaimed animator and director, has gained international recognition for his innovative use of color and unconventional visual storytelling, particularly in digital animation. This study examines Mielgo's representative animated works—The Witness, The Windshield Wiper, and Jibaro—from a colorological perspective, analyzing how his distinctive chromatic strategies enhance narrative structure and emotional engagement. Specifically, The Witness employs extreme complementary contrasts of neon colors within urban environments to evoke simultaneous feelings of anxiety and allure. Conversely, The Windshield Wiper utilizes muted pastel palettes with subtle shifts in brightness and saturation to convey introspective emotions characteristic of modern urban life. Lastly, Jibaro integrates symbolic chromaticism through metallic gold tones contrasted against serene natural hues, visually allegorizing themes of greed, toxic relationships, and colonial violence. Through these analyses, this paper highlights how Mielgo's sophisticated integration of traditional color theory with contemporary digital technologies expands the expressive possibilities of animation. Ultimately, this research underscores the critical role of color as more than mere aesthetic decoration; rather, it functions as a powerful narrative device capable of profoundly shaping viewer perception and emotional immersion. The findings further suggest meaningful implications for future creative practices across diverse digital media platforms including animation, gaming, VR (Virtual Reality), and XR (Extended Reality).
