I like to emphasize star colour in my images, but haven't had to do anything in particular to capture such colours. I take 5min subs and naturally the brighter stars will be saturated in their cores, but all stars are recorded as Gaussian profiles so regardless of saturation they still contain colour information within a certain radius from the centre.
When I stretch my data I take care not to saturate the brightest areas, including the stars. This allows for colour to be maintained during processing.
