I’ve read once in an article that depending on the tint of one’s eyes _ grey, brown, blue, or green_ one sees colors in a different way. This means that each individual discerns unique and characteristic shades and types of pigments that others probably don’t even know about.
It is interesting to imagine that what appears, for example red to one person, could actually be what another would call blue or purple. There is therefore no true color in the universe, for these are only our brain’s individual interpretations of what we see.
In fact, the same phenomenon happens for our ability to hear, to smell, as well as our ability to taste. The only common sense that living beings possess is the sense of touch, which never changes whether one is a teenage girl, an old man, or an infant. All individuals would therefore be able to identify the same objects by the single sense of touch, because it is something that takes place outside of the brain. Even though the information passes through our mind, the contact is always made by the outer parts of our body, whereas odors, sounds, and images are identified thanks to certain parts of our brain.
Thus, we live in a world where most things could clearly be an illusion. Nothing is certain, nothing is real, and all we can do is make a guess at what this world is truly about.
