Appearing as a whiteish yellow while overhead and redder when at the horizon, it's clear that the question "what color is the sun?" is actually more complex and difficult than it may initially sound.

Each color in the visible light spectrum has a different wavelength and energy level. Blue light has shorter wavelengths and higher energy than other colors. Blue light is located in a narrow ...

Scientists for years have made small red and blue lasers, but other colors, including green ... miniature lasers in this region of the visible-light spectrum as the "green gap." ...
