In 1672, Isaac Newton conducted experiments with prisms and demonstrated that white light is composed of a spectrum of colors. This discovery laid the foundations for modern optics and challenged the prevailing theories of light at the time. Newton's work not only advanced scientific understanding but also influenced the fields of art and color theory, as it revealed the complexity of light and color perception, ultimately leading to innovations in various scientific disciplines.

Newton's discovery of the spectrum of light inspired poets like William Blake and John Keats to explore themes of perception and beauty. The rainbow became a potent symbol in Romantic poetry, representing the interplay between science and art, as well as the emotional spectrum of human experience.
