The correct answer to this open question is the following.
As a room-temperature object increases in temperature, it begins to glow. Describe the progression in colors as the object heats up. Ultimately, what happens to the glow if the warming continues to nearly infinite temperatures is the following process.
In the beginning, the object is at room temperature and starts to warm up. As soon as this happens, it starts to turn to the color red, which means it glows red. As the object gets warmer, it starts to turn into many colors. It continues to get warmer and glows in blue, green, yellow as if it was a rainbow. But it comes a moment in the process of heating that the object turns into black due to the photons it is emitting have short wavelengths and human eyes do not see these waves.
