Colour-temperature settings change the display’s white balance. A cooler mode often appears bluer, while a warmer mode can look less blue by comparison. Your eyes adapt to the previous setting, so judge familiar material after a little viewing rather than deciding from the first second of a switch.
Use neutral objects and faces
A white shirt, grey wall and natural skin tones are more useful than a saturated animation or a brand logo. Strong room lighting can also influence perception. Keep colour saturation and dynamic processing stable while comparing temperature settings, otherwise several changes may be mistaken for one effect.
Avoid a universal slider recipe
Manufacturers use different labels and starting points, and individual panels can vary. A cinema-oriented preset may provide a useful baseline, but copied red, green and blue gain values are not a substitute for measuring the actual display. Do not adjust advanced controls randomly to make one actor’s face look preferred.
Allow a sensible adaptation period
A neutral-looking image may initially seem yellow if the previous mode was strongly blue. Watch a familiar sequence, then compare again. If one input remains visibly different from others, check its stored picture mode and source settings before assuming the streaming service has changed every programme’s colour.
