Heye Sophia's List: Revisit

• However, I would suggest that most discussions of rearrangements of color qualia severely underestimate how much structure comes along with our color perceptions.
• colors are part of a three dimensional space of colors, a space having certain well-known features. The space is spanned by a red-green axis, a yellow-blue axis, and a black-white axis. These three axes have opponent colors at opposite ends, and these extreme ends of the axes are pure or primary (i.e., not being built via a combination of other colors). All the colors we know of are a perceptual combination of these three axes.
• Colors are not only intricately connected to one another in a space, but are linked to many other aspects of our mental life, including other sensory modalities (e.g., a "red sounding trumpet") and emotions.
• I have argued elsewhere that our color-vision eyes are oximeters like those found in hospital rooms, giving us the power to read off the emotions, moods and health of those around us.
