Since the three types of cones have different sensitivities to light, does this mean that each person perceives color differently due to the likely different proportions of each type of cone within their eyes? More specifically, is there any distinguishable way to know whether what I assign the label as "red" is the same color as what another individual sees as "red"?

To expand on Tyler's question, there's this theory called "qualia" that refers to the subjective, first-person experiences of sensory perception, such as the color of red. Even though two people may agree on what to call a color "red," they may be experiencing completely different subjective experiences of that color. Professor Ren Ng briefly mentioned in class how there is no evidence that we all have the same reds. It's an interesting perspective that gets into the nature of human consciousness.

To further expand, the concept of inverted qualia is also used to justify the subjective experience of color perception. In qualia, two individuals may agree on calling something red but experience it differently. In inverted qualia, there may be something red that the first person calls red, and the second person may call green based on their conceptions of color. Again, this is another way to show how color perception is subjective and there is no definitive way to know how other's see color largely because there is no objective truth to color on a personal level.

Assuming we all see the same colors through the same types of cones, it's also interesting to see that even the same kinds of cones may not "detect" the same color, since cones are biological and may absorb a different distribution of frequencies at different relative responses.
