We present integrated colours, integrated spectral
energy distributions, and absorption-line indices, for
instantaneous burst solar-metallicity binary stellar populations
with ages in the range 
Gyr. By comparing the results for
populations with and without binary interactions we show that the
inclusion of binary interactions makes the appearance of the
population substantially bluer – this is the case for each of the
quantities we have considered. This effect raises the derived age
and metallicity of the population. Therefore it is necessary to
consider binary interactions in order to draw accurate conclusions
from evolutionary population synthesis work.
