The three room of Carlos Cruz-Diez's <i>Chromosaturation</i>'s immersive 
environment served as a visual color wheel.  Each room was lit with 
different colored fluorescent lights.  Looking at how the light changes 
by the distance to the source and how the colors mix near the doorways 
showed the full gradient of color and lack of boundaries.  Color is a 
continuous space, a continuous experience.
