Why stars are so Blue/Cyan?

I think they are blue because the exposure took one hour and twenty minutes in total. The scope was going slowly out of focus due to temperature shift. Since blue was the last exposure, the blue image had the more bloated stars. When I combined this resulted in a blue halo/cast around every star.
