WebA white dwarf is very hot when it forms, but because it has no source of energy, it will gradually cool as it radiates its energy away. This means that its radiation, which initially has a high color temperature, will lessen and redden with time. WebWhen they are "born" white dwarfs have surface temperatures of ∼ 100, 000 K. This radiates across the whole visible spectrum and our eyes would perceive this as a blue-ish-white. Even after a billion years, the surface temperature would be of order 10,000 K and the white dwarf would still appear white.
