This color is a bit of a mystery. It is not part of the rainbow. Scientists call it an extra-spectral color. This means no single color in the light spectrum is magenta. Instead, your brain makes the color. This happens when your eyes see red light and blue light at the same time. Your eye has tiny parts called cone cells. These cells help you see color. When your brain gets signals from blue cones and red cones, it sees magenta.

Magenta has a long history. In 1859, a chemist named François-Emmanuel Verguin made a pink-red dye. He first called it fuchsine. Later, the name was changed to magenta. This was to honor a battle fought in a town called Magenta.
