There is no such thing as sound or color. These are just imaginary representations crafted by our brains as a way of hearing and seeing our world.
There is no green to the grass, yellow to the sun, or blue to the ocean: No A flat, G sharp, or C major in music—just different wavelengths of light and frequencies of moving air.
In the physical world, light and sound are not grouped as colors and tones. It is only in our mind’s construct to help us make sense of the world we see and hear these poetic representations of wavelengths and frequencies.
It should be of no surprise then that changes in wavelength or vibrational patterns—even the smallest of changes—present themselves as differing colors or sound patterns when our brains reassemble various external inputs and stimuli.
Just knowing that everything we see and hear is a mental construct unique to each of us should be food for thought when it comes to suggesting there’s an absolute sound or vision.
It is, after all, just a personalized illusion.
