Apparently Blue Light Reduction mode in iOS 9.3, also dubbed Night Mode, has a hidden trick up its sleeve that should make many that care about their display's color temperature happy: it finally allows users to set the color temperature of their display to their personal preference. What does this mean exactly? That when iPhone 7 comes out, whenever somebody on the forum complains that the display is too "yellow" (warm) for their liking we can point them to setting the display's color temperature to a cooler (bluer) temperature, which is now possible.

It was a long time coming since many iPhones' color temperatures are set slightly differently off the production line and thus there have been disparities even between two of the same model side-by-side, but Apple has fixed this issue and hidden it into Night Mode for us display enthusiasts :).

Personally I prefer a warm display, and heck one of the reasons I didn't buy an iPad mini 4 when it was on-sale for under $299 was because the display was too cool compared to my iPhone 6s Plus's warm display, which I love.

Nah, the coolest setting in night shift mode is still warmer than the base setting of your screen. So you can only go warmer, not cooler.

Ah, I assumed Apple had baked it in for those that want an increase in blue light. I'm not on the 9.3 beta but this is welcome to me for if I receive an iPhone/iPad that's not warm enough :).

It doesn't work that way. Even with the slider all the way to the cooler setting, it's still warmer than having Night Shift off. You can't adjust display temperature sadly.

Yep, you're right. This feature can only make your display warmer than it already is.

One interesting observation is that when this setting is turned on, there's a color aberration when scrolling text up and down. Blue text looks purple while you scroll (and only while you scroll) and black text kind of glows a little with red fringing on the edges of characters.... And white text like when you use the dark Tapatalk theme turns brownish.

The bar is definitely misleading considering it is blue on the left and yellow on the right. That could certainly be changed.
