Another vote for Redshift. Use Flux on work PC and Redshift on laptop. The colour transition seems to be a lot more subtle with Redshift and I find it easier to adjust. On the other hand, the change feels very sudden with Flux. Often use my laptop in work, but I suppose it could well just be a difference in lighting between home and the office, as others have mentioned. Maybe my eyes deceive me.
