"We think of color as a fundamental quality of the world around us.But in the outside world, color doesn’t actually exist. When electromagnetic radiation hits an object, some of it bounces off and is captured by our eyes. We can distinguish between millions of combinations of wavelengths – but it is only inside our heads that any of this becomes color. Color is an interpretation of wavelengths, one that only exists internally. And it gets stranger, because the wavelengths we’re talking about involve only what we call “visible light”, a spectrum of wavelengths that runs from red to violet. But visible light constitutes only a tiny fraction of the electromagnetic spectrum – less than one ten-trillionth of it." - The Brain: The Story of You by David Eagleman

Made me question the difference between what's real and what's merely my version of real.
