We, as viewers, are constantly bombarded with visual information. Light of seemingly infinite arrangements of intensities, wavelengths, and spatial arrangements enters our eye, impinges on the surface of our retina, and through a complicated and fascinating process, it results in conscious awareness of a visual world. However, the brain does not necessarily translate physical properties of the world in a one-to-one manner. Rather, perception involves a complicated process of thought and problem solving in which the brain attempts to utilize physical information in an optimal manner. Through a series of experiments, I have explored one of these complicated processes: Color Constancy. The brain makes estimates of the light reflecting off of a surface and of the light source illuminating the surface. Perception of the object’s color depends on both of these factors. I have attempted to uncover the nature of the color constancy mechanism’s ability to integrate contextual information over space. Specifically, I have explored the interaction of foreground and background colors and the way that they each affect the appearance of other colors in the scene.
