If you gathered enough neutrons to be seen, what would it look like?

IF it were possible what would it look like.

It wouldn't really look like anything, because light has minimal interactions with neutron. It would essentially be a diffuse gas. There would be a lot of beta radiation coming from them, so if you put all the neutrons in water together you might see a blue glow.

If you had a neutron star, it would look very bright due to its extreme temperature.
