As the forms of office work and the concepts of work continue to evolve, the function of color in office spaces has gradually transcended the aesthetic level, beginning to participate in the deeper construction of spatial experiences and organizational expression.

It reveals the significant trend of color moving from a subordinate element to a spatial language, providing a realistic framework for contemporary office space color design.
