As the title says, any chance of this being introduced, like it has been for iOS? It's brilliant to be able to change the colour tint of my iPhone and iPad. My screens are now not yellow at all and I've been able to match the 2 screens near identically (my iPad used to be much more yellow than my iPhone, for example). It would be great if I could do the same on my MacBook. The current default display calibration isn't very good, and I can't get it to look similar enough to my iPhone/iPad.
