An equinox is a point in time when the sun crosses the celestial equator and day and night are equal in length everywhere on earth. The Equinox Series conveys this symmetry through color and geometry. The limited palette reflects the changes in atmospheric color that I observed during a Spring residency at the Catwalk Institute in the Hudson River Valley. The central patterns of concentric circles, created using the Fibonacci sequence, make visible the passage of time when the works are installed as a series.
