The visible and the invisible

Gertrud Olsson

This study deals with the changes in color that arise in space, primarily simultaneous contrast in three dimensions. The typical account of simultaneous contrast is that the contrast phenomenon occurs between two or more color surfaces seen together, thus affecting one another. The overarching question of the study is: How do we perceive the phenomenon of simultaneous contrast in space? The work analyzes how the concept of simultaneous contrast is used historically, and also examines its importance in a cultural context. The study of color contrast phenomena includes color as a material, as well as the visual perception of color, and is based on three philosophical theories, one per chapter.
