Adaptive color tone uses the phone's ambient light sensor to adjust your phone's display colors to your physical environment. It is supposed to make colors more natural and make the display easier on the eyes.
I personally don't use it because I prefer to keep colors vibrant and consistent.
Hey, current s24ultra user here. So yeah I had that setting on for a bit and im not entirely sure whether I like it or not. It does really reduce eye strain but it does make the screen look a little more white washed and whenever I turn it off I can see how much blue is in the screen. So im not sure whether the setting does make the colors look more natural or whether samsung screens are just really blue. But either way I havent seen too much impact on battery
