You don’t. To a blind person touch texture and sound become your main ways to interact with the world. Its hard for people who can see to imagine a completely different mode of human experience. A truly blind person has more appreciation for the other senses they do have. I have heard of some blind folks learning what colors look like through psychedelics. their brain registers colorful flashes due to the visual cortex being stimulated since psychedelics make your brain parts all work together in ways they otherwise wouldn’t.
