In Berman’s mind, information and knowledge flow like an unseen current between people and media in the library environment. This print is one of ten that visualizes this phenomenon in the ebb and flow of color across them. While the series has a cohesive visual effect when displayed together, each individual unit has its own unique characteristics. In the fourth of the series, vast hues of blue and green create deep wells of visual attention punctuated with yellows and oranges. Within each frame, the layering of color creates new shapes and hues that add to the overall flow of the work. One can imagine the layers of color to be like layers of information in the mind, crossing to create new colors and new ideas.
