The number of distinct hues observable within a rainbow is often cited as seven. These are traditionally identified as red, orange, yellow, green, blue, indigo, and violet. However, the perception of color is subjective and influenced by individual vision and environmental conditions. The distinction between each shade is not sharply defined, but rather a gradual transition of wavelengths across the visible spectrum.
Understanding the components of visible light and its refraction through water droplets holds significance in various scientific fields, including meteorology, optics, and atmospheric physics. Historically, the selection of seven colors has been attributed to Isaac Newton’s work, who drew parallels between the number of colors and the seven notes of a musical scale. This convention, while widely accepted, remains an approximation of the continuous spectrum present in a rainbow.
