John Hopkins University news release:
In a new paper published in the Journal of Experimental Psychology: General, researchers led by cognitive psychologist Jonathan Flombaum dispute standard assumptions about memory, demonstrating for the first time that people’s memories for colors are biased in favor of “best” versions of basic colors over colors they actually saw.
For example, there’s azure, there’s navy, there’s cobalt and ultramarine. The human brain is sensitive to the differences between these hues —we can, after all, tell them apart. But when storing them in memory, people label all of these various colors as “blue,” the researchers found. The same thing goes for shades of green, pink, purple, etc. This is why, Flombaum said, someone would have trouble glancing at the color of his living room and then trying to match it at the paint store.
This is interesting. There must be more to it though: I have excellent color perception in the moment, but I’ll often misremember red as green, etc.
