If that's the surface temperature of a black body, then it would have,
according to Wien's law, an emission peak at around 1,073 nm. This is infrared.
A star can be taken as a black body. Stars with such a low surface temperature
are in the spectral class M. Examples are Antares (3,400 K) or Proxima Centauri
(3,040 K). Both are quite reddish or orange.
Wikipedia offers this scale:

2,700 K is represented by a colour of
#FFBA69 = 255 186 105
(according to my screenshots programme)
A bit of googling reveals:
