Is color constancy critical for object recognition? At what point does changing the color of familiar/previously seen objects make them unrecognizable?

Does the ability to perceive color differently depending on 3-D structure come pre-built into the visual system or does it require visual experience? Would someone with newly acquired sight perceive the colors in a different way than the subjects in the Bloj et al experiment did?

How much does the knowledge (experience) of specific object matter in the case of color constancy? Does the ability to perceive color constantly only relate to how color itself change under different illuminant?

How does language influence our perception of color ? One of the games my nephew plays is essentially describing the right color of a block, but if I show him a different shade of orange/green etc he can't tell me what the color is. At what point do we obtain the ability to distinguish between different shades of color and describe something as reddish orange or blueish green etc ?

Albers notes the flaws of visual memory, such as weakness of it and memory color, and also the instability of color itself in our perception — anything from colors in contrast to lighting temperature. With all this variability and instability should the goals of exploring color vision in art and science be to witness these variances or seek to fool the eye?

The Albers (1963) reading mentions that visual memory is poor in comparison to auditory memory, especially regarding remembering distinct colors. What features of the vision might result in poorer recall? What features of the auditory system allow for better recall?

Albers mentions several artistic movements of form and construction in art. Every year colors are “on trend” or not, with efforts such as a Pantone color of the year. How can we define movements around color?

This is probably not directly related to the discussion of color in the medium of light, but in the book called the secret lives of color we can follow the history of how humans started creating art with different colors etc. And that got me to wonder about the emotional and cultural perception of a color - for example red/yellow is considered auspicious/serene in some cultures and can indicate distress in others. I wonder if the emotional cues attached to colors influence our perception of colored objects.

Both the Albers (1963) reading and the Smithson (2005) reading mention that our ability to discriminate colors exceeds the number of discriminations represented in our vocabulary. I’m curious about the extent does language influences our perception of color. There is a tribe in Namibia (the Himba tribe) who are able to distinguish between more shades of green, possibly because they have more words for types of green than English. Meanwhile, individuals in the Himba tribe perform poorer when asked to discriminate between blue and green, which is interesting because the Himba have no word for blue. Are there other instances in which our language might influence our perception? If we had more words for different color shades, would we be better at recalling and/or distinguishing between them?
