Introduction
Most people see the world in shades of about a million different colors. Though they may not be able to identify each one, more a result of social constraints [1] than anything else, our biological thresholds seem to indicate that this is a shared ability.
My Blue or Your Blue
Previously, scientists believed that most people’s perceptions of colors were similar; that is to say, my “blue” looks the same as your “blue.” However, it seems that this may not necessarily be the case. In other words, your “blue” could be my “orange.”
While color perception begins with the limitations of the eyes, much of the processing ultimately takes place in the brain, where it fills in lots of missing information and parses the raw material that it takes in from our senses. Many parts of this process are not well understood, and so, indeed, peoples’ perceptions of colors may be slightly to significantly different.
Differences Observed
As of late, we have been able to identify gender-differentiated perceptions in colors, as well as color perception inabilities (“color blindness.”) In general, men have more difficulty distinguishing finer shades of color, whereas women are generally more capable of doing so.
Psychology of Color
You might be wondering, then, about the way colors influence our feelings. For example, some people associate red with hot, and blue with cold, or perhaps with joy and sadness respectively. Studies seem to indicate that these are largely a product of socialization [2], and not something inherent to the way we perceive colors.
