It depends on your interpretation of what a star is:
The coldest star on the main dequence is a red dwarf.
The coldest star off of the main dequence is a red giant.
The coldest stellar remant is a black dwarf.
However, there stars that cannot fuse hydrogen, but emit light: They are:
- Brown dwarf < 2,000 oK
- Methane dwarfs < 1,300 oK
- Sub Brown Dwarfs < 600 oK
- Black dwarf 2.3 oK - although none have been observed - See related link.
