Can purple become blue? The surprising aswer is YES
Human mind categorises everything from people to objects, to sounds, colours, odours, etc. However, these categories are not set in stone, as one might think, and can be influenced by experience. A recent study published in Science demonstrated how people’s perception of what is blue and what is purple changed with the change in the proportion of the other category items. That is, dots that were previously categorised as purple were later categorised as blue when the number of other blue dots dramatically decreased. Read more here how this effect applies to other types of categorisation.
