In the 1990s, Donald Judd continued his profound exploration of space, form, and color, although this decade was truncated by his death in 1994. Judd's work remained grounded in the principles he established earlier in his career—creating pieces that emphasized the relationship between object, viewer, and environment. His works from this period are not only reflections of his matured vision but also indicators of directions he might have further pursued had he lived longer. During this time, Judd further solidified his legacy with significant installations and projects, notably continuing his work with the Chinati Foundation in Marfa, Texas. The foundation, which he established to house large-scale installations by himself and selected peers, became a pivotal part of his work, allowing him to create permanent installations in dialogue with the landscape. This emphasis on the integration of art with its surrounding environment highlights a consistent theme in Judd's work: the consideration of space as a material as essential as the physical components of his sculptures​ (The Art Story)​. Judd's commitment to creating environments that provoke a direct, unmediated experience of art for the viewer was complemented by his ongoing exploration of industrial materials and processes. He continued to work with materials like aluminum, steel, and Plexiglas, pushing the boundaries of these mediums to explore new visual and spatial effects. Judd's work in the 1990s, characterized by its minimalistic aesthetic and the precision of its execution, remained a significant influence on contemporary art, architecture, and design. His approach to art making, which involved the use of commercial fabrication techniques and materials, underscored a broader shift in contemporary art towards conceptual and process-oriented practices. This methodology allowed Judd to explore the object's intrinsic qualities—form, color, and materiality—without the mediation of traditional art-making techniques​ (MOMA)​. By the time of his death, Judd had established a complex body of work that continued to challenge and expand the definitions of sculpture and installation art. His insistence on the autonomy of the art object and its integration with the surrounding space has left an indelible mark on the landscape of modern and contemporary art, influencing generations of artists, architects, and designers. Through his writings, installations, and the ongoing work of the Chinati Foundation, Judd's critical and creative legacy continues to be a source of inspiration and exploration​ (MOMA)​.
