When a solid is heated, the first color it emits is red. This is because red light has a lower frequency and longer wavelength, so it requires less energy to be emitted by the heated solid. As the temperature continues to increase, the solid will emit yellow, then white, and finally blue light as it becomes hotter and hotter.
