I would use colour, but only when you have got monitoring with colour. Coulor works in 4:4:4, so its the best choice.
Otherwise I would use colorista (Magic bullet), which is a very good tool, the looks are great.
If you haven’t got colorista, go with FCP colour correction together with procamp filter.
Use Proc amp first, then 3Way coulor correction.
I hope this helps
