The process that increases the thermal energy of atoms in a star and impacts the color of light a star radiates is the conversion of mass into energy during nuclear fusion. In the core of a star, hydrogen atoms fuse together to form helium under extreme pressure and temperature, releasing vast amounts of energy in the form of light and heat. This process not only raises the thermal energy of the atoms but also determines the star's color based on its surface temperature.
