The project of a tool that uses Fechner's colors for the foundations of lighting and color design

This article presents the project of a tool aimed at elucidating the nature of color as a psycho-perceptive sensation existing solely within the human mind. Aimed at novice designer, this tool delves into the intriguing phenomenon of Fechner's colors and their implications for our understanding of color perception. The phenomenon of Fechner's colors is first introduced by explaining its importance for understanding the psycho-perceptive nature of color. We then delve deeper into the current possible scientific explanations underlie Fechner's colors visual perception. The design of the experiment is then illustrated, carried out using a black box under controlled lighting conditions, intending to be able to directly observe Fechner's colors rather than observing a representation of the experiment on the computer screen, which could make some subjects doubt the presence of colored makeup.
