If you don't consider relativistic reddening, the temperature of a fresh neutron star would give it a black body color in the very hard ultraviolet. It has been suggested that neutron star material is a nearly perfect conducter of heat and electricity, and that it has a very high specific heat. The actual temperature should be somewhere around 10 to 100 million degrees K, C, or F, all are close enough. The relativistic reddening effect will vary according to how close it is to blackhole mass. It can have any range from increasing wavelength by about 10 percent to almost complete photon capture. If you ever get a cold neutron star, it should appear like a mirror that makes everything reddish. But don't hold your breath, they don't get don to room temperature very quickly. Also, you should note that there is almost always a lot of matter around a neutron star, which would tend to obscure your view of it as a black body. You would tend to see the black body temperature of the last opaque layer of material.
