Due to photoreceptors not having access to full spectral information about light, and color sensitive photoreceptors being primarily in the center of the retina, our brain has to fill in a lot of color information. Are there any cases/illusions where we can observe this “filling in”? Does it have anything to do with synethesia? How about Herman Grid Illusion?

When the same color is placed on 2 different backgrounds, why are certain colors more susceptible to change (more likely to be influenced) than others?

Colorblindness isn't all that rare. Couple that with the fact that many differences in ability often are possible because they were coupled with some sort of evolutionary benefit (e.g. sickle cell patients/gene carriers are less likely to contract malaria, certain learning disabilities come with a variety of cognitive benefits like temporary hyperfocus and the ability to more quickly heal from trauma with respect to memory/etc, and those born without certain sets of molars will never have to endure wisdom tooth surgery or infection), it's easy to wonder: what evolutionary and or biological triumphs and benefits might be associated with colorblindness?

Why is color seen as an artistic tool to express emotion? Where do we get the ideas, for example, that blue is sad and that red refers to love? Are these ideas evolutionary or influenced solely by culture?

Do you think Albers comparison in the reading between auditory and visual memory is fair? Is it true that we are less able to discriminate small color frequencies than small frequencies of sound?

How much does language play into color perception? In the reading it talked about how most humans have some difficulty in distinguishing lighter/darker hues of the same color. Since different languages have a different number of categorized colors, does the languages we know affect how well we can distinguish these differences? For example, in english we have the category ‘blue’ and then just use light/dark to distinguish the different blues. However, in Russian the name for ‘light blue’ is completely different than the name for just blue. Would this cause Russian speakers to be able to distinguish light blue with more ease?

Albers suggests we rarely see a single color, rather colors are more often presented in a continuous flux. Why then is it so simple to parse all colors into < ~30 discrete colors? When we describe our world in a finite set of colors it seems like we are abbreviating what we are actually perceiving about objects and their environments. Does this abbreviation impede our ability to perceive the world more deeply and convey that perception to others more accurately?

How do you think modern technology and constant engagement with electronic visual displays, as well as the physical limitations of those displays, impacted our vision as humans in the era of the screen?

given the relationship between art/sensory inputs and memory, have there been explorations in therapeutic practices that involve art for illnesses such as Alzheimer’s or dementia?

how do you think associative learning relates to experience and feelings, e.g. in higher cognitive tasks?

What role does our visual history play in seeing color? The readings discussed the role of illumination, contrast, shape etc on color perceptions., but as our demonstrations in class illustrated our knowledge of what a color an object should be can also influence what we perceive. How can this influence be taken into account and is this something that can be modeled/studied?

How is color perception impacted by nurture as opposed to nature? To what extent does the way we are raised impact how well we can “see” color?
