Created in 1974, this work is part of Cruz-Diez's celebrated *Physichromie* series, in which the Venezuelan artist explores the autonomous behavior of color in space and time. Precisely arranged vertical strips of acrylic and laminated plastic are mounted on a wood panel, generating shifting chromatic relationships that transform as the viewer moves before the composition. The work embodies Cruz-Diez's lifelong investigation into color as an unstable, living phenomenon rather than a fixed property of objects.
