Plants use chlorophyll to perform photosynthesis, but certain things like cold temps and UV light break down chlorophyll. Instead of cholorophyl a plant can produce anthrocyanins for photosynthesis and these are red/purple compounds that do the same thing. Lots of cultivars purple during flowering. Cold temps help promotes these colours.
