Personally, I found scheduling the warmth setting is far more efficient and easier than fiddling with it every time there is change in light conditions. Scheduling the warmth setting would mean that you Kindle Oasis to turn a couple of shades warmer between a specific period of time. And if you don't want to play with your display settings every time you pick up the Kindle Oasis, you can also schedule the warmth settings. Of course, you will have to play with the brightness and warmth settings a bit to get the right shade on screen, but that's not exactly a difficult task. Interestingly, this setting also allows you to achieve a screen colour that resembles the real books. Just like the brightness settings, there are 24 points to the warmth settings which allow you to adjust the screen warmth from zero, which is how the screen would look without the setting, to 24, which is a deep shade of sepia with the screen resembling an old book. The 10th generation Kindle Oasis comes with warmth settings, which enables you to better adjust the colour of screen as per your comfort level.

The most important feature that is really separates the new Kindle from the old is the warmth settings.
