  Binary stars are important for a full understanding of stellar evolution. We
present a summary of how predictions of the relative supernova rates varies
between single and binary stars. We also show how the parameter space of
different supernova types differs between single and binary stars. We then
consider an important question of how to infer a supernova progenitor's
properties from pre-explosion imaging and present rescent work of producing
synthe tic colours for our stellar models to make a direct comparison with any
detections or limits obtained on supernova progentiors from pre-explosion
images.
