"The Pop Microbial Phantasm": A Dialogue Between Replication, Color, and Medium. Marilyn Monroe as the Core of Replication hoosing Marilyn Monroe as the central image for this series is not merely a homage to Andy Warhol's classic works, but more profoundly reflects the multiple meanings of replication in contemporary contexts. Monroe herself is the ultimate symbol of repetitive reproduction and consumption in 20th century popular culture, her image having undergone transformation from a real person to a media-constructed idol, and then to an artistic reproduction. By reconstructing this already heavily reproduced image through microorganisms, the work creates a replication of a replication, forming a self-referential postmodern echo. As a Hollywood iconic figure, Monroe's life trajectory implies a duality concerning surface and depth, reality and illusion, which subtly echoes the growth process of microorganisms in petri dishes: "the transformation from invisible to visible." The choice of this image also critically examines how celebrities are reproduced, consumed, and regenerated in popular culture. Dialogue with Andy Warhol's Prints Andy Warhol's Shot Sage Blue Marilyn series uses screen printing techniques to challenge the uniqueness and aura of artworks through mechanical reproduction. This work, however, offers a biological response to Warhol's mechanical reproduction aesthetics through the growth process of living microorganisms. While Warhol's prints emphasize standardization and industrialization of reproduction, the microbial paintings in this work introduce the variability and unpredictability of life, creating a new paradigm of "organic reproduction." Warhol's work explores the boundaries between commercialization, popular culture, and art. This work further expands this thinking by merging life science, artistic creation, and commercial symbols. If Warhol's reproduction was a response to mass culture in the industrial age, then this work's microbial reproduction represents forward-thinking about the relationship between identity, replication, and variation in the biotechnology era. Medium Differences Between CMYK and RGB The CMYK four-color model in traditional printing and the RGB petri dishes used in this work form an inspiring contrast. CMYK, as the standard for the printing industry, represents the precision and standardization of mechanical reproduction; RGB, as the foundation of digital visuals, symbolizes virtual reproduction in the electronic era. The choice to create on RGB three-color petri dishes is not only an attempt to merge digital and biological media but also a historical dialogue between different reproduction technologies. Unlike the visual effects produced by color overlapping in CMYK printing technology, the microbial colors in RGB petri dishes are naturally presented through living activities, creating a unique visual language. In traditional prints, color overlapping is static and controllable; in microbial petri dishes, the generation and change of colors are dynamic and semi-controllable. This contrast reflects the artist's exploration of balance between creative control and life autonomy. The use of RGB petri dishes in the work also implies reflection on the digitalization of contemporary visual culture. In the digital age, the reproduction and dissemination of iconic images have transcended the limitations of physical media, becoming unlimited and instantaneous. By transforming this digital color mode into physical biological cultivation, the work achieves a reverse process from virtual to material, questioning our perception of the essence of reproduction. Through this dialogue between media, the work not only connects Warhol's era of mechanical reproduction with contemporary biological reproduction but also establishes historical continuity between printing technology, digital technology, and life science, providing a new dimension for artistic reproduction theory.
