Color feels like one of the most basic features of the world around us, but underneath that familiar experience is something surprisingly physical.
Every visible color corresponds to a particular range of wavelengths, meaning the difference between red, green, blue, and violet can be described using actual measurements of electromagnetic waves. Those wavelengths are incredibly small, yet tiny changes in them produce completely different colors to our eyes.
It is one of those ideas that connects everyday experience with the deeper physics of light in a way that makes color feel much stranger than it did before.
Perfect for anyone curious about visible light, wavelength, the electromagnetic spectrum, color perception, or the physics hiding behind the colors we see every day.
