One of the big new features in the latest version of iOS is the ability to change the temperature of your display with a feature called Night Shift. Believe it or not, but the $200 honor 5X allows you to do the same thing. Well, mostly.
Color temp can be adjusted opening the Settings app and selecting Display > Color temperature > and adjusting the slider. Moving it to the left will make for a warmer image (useful when viewing during nighttime hours), while the right side more blue-ish and cool.
Play around with it for a bit. If you feel like you messed things up, you can always click the "Default" button to revert your changes.
