The Custom settings are not meant to represent any kind of calibrated color temperature, but rather to provide the user with some “punchier” settings than the calibrated ones. You can reset any of the color temperature settings, not just the Custom ones, but it is recommended to leave the Low and High alone, as it may come in handy to know what the original factory settings are, an
