Very red point source -- a red giant?

This point source is very red. Could it be a red giant star? Or a quasar?

Could be a low-mass star. Up and to the right of that one is an even redder star with an SDSS spectrum – an L dwarf star (brown dwarf).

Quasars often show up as blue – they emit strongly at many energies.
