No, the plasma of the sun emits radiation according to blackbody radiation in addition to having spectral absorption lines from its atmosphere. See here for better details on blackbody radiation: This is why the Sun appears yellow, its peak output wavelength is in the yellow range because of its temperature. This is known as Wein's law, a simple relationship between the temperature and peak output wavelength of a hot object.
