How much do you know about the science and philosophy of color perception?

• Color is the visual perception of the aspect of a surface or light, based on the spectral distribution of light that stimulates specialized nerve cells called cones.
• Color can be approached chemically, physically, physiologically, psychophysically, cognitively, and philosophically.
• The chemical approach produces nomenclatures of products and shades and notes the possibilities of mixing.
• The physical approach defines light as electromagnetic radiation defined by its spectral analysis.
• The physiological approach defines color by the three intensities resulting from the filtering of light by the three filters corresponding to the three types of cones in the human eye.
• The psychophysical approach defines color as a perception responding to light stimuli.
• The cognitive approach defines color as a sensation associated mentally with objects that produce the most marked expression of color.
• Identifying color sensations with categories is a learning process that allows conscious use of colors in signs and involves their unconscious participation in symbols.
• The vision of colors is a philosophical problem since all approaches give a definition of color that applies only with significant restrictions.
• An infinite number of physically different lights can result in the same color perceived by the human eye, which can be represented by a three-dimensional colorimetric model.
