In general, the so-called colour temperature is a measure for the colour tone of the white point within an image. Based on the temperature unit Kelvin, a nominal assignment is made, which states whether the light appears rather warm, in other words yellowish red, or cold, bluish. The “right” colour temperature depends on the preferences of the viewer and the content.
Picture mood is influenced by colour temperature
From an optical point of view, this is the degree of warmth that a black body theoretically has to reach in order to take on a certain colour. The higher this value, the bluer and colder the tone. This underlines a dramatic mood. A low level produces warm, yellowish light, creating a cosier atmosphere.
Values above 5,300 K therefore represent daylight white or increasingly cold white. Within the range of 3,300 to 5,300 K, the result is a neutral white. Warm white is achieved at 3,300 to 5,300 K. The “K” stands for the unit of measurement Kelvin.
Colour temperature also depends on content
A properly calibrated colour temperature on the TV device ensures that viewers experience the content as the creators intended. The standard colour temperature of 6,500 K, also known as D65, is used in film and television production and corresponds to the average daylight colour.
Since this temperature is closest to the artistic intentions of the production team, the filmmaker or cinema mode of TV devices is also adjusted according to this. For sports broadcasts or news programmes, on the other hand, which are often shot in brighter, more artificially lit environments, a higher and thus colder colour temperature may be closer to the original.
