Purple feels like one of the most obvious colors in the world. It appears in flowers, clothes, bruises, branding, sunsets, and royal symbols, so the idea that it is somehow “not real” sounds like a trick.

But the science is more interesting than the headline suggests. Purple is real as an experience, but it is not a spectral color in the same way red, green, blue, or violet are. It has no single wavelength of visible light; your brain creates it by interpreting signals from opposite ends of the spectrum.
