The color of spring rain is typically a light, translucent blue. This perception is influenced by the way raindrops interact with sunlight and the atmosphere. When raindrops fall, they scatter sunlight in all directions due to a phenomenon called Rayleigh scattering. This scattering is more pronounced for shorter wavelengths of light, which are blue and violet. However, the human eye is more sensitive to blue light, so we perceive the scattered light as blue. Additionally, the atmosphere can absorb some of the shorter wavelengths, leaving the blue light to dominate the color of the rain. According to a study by the American Meteorological Society, the color of rain is primarily determined by the scattering of sunlight by water droplets, with the blue light being the most visible due to its shorter wavelength and higher scattering angle.
