Editing Color temperature (section)

The [[NTSC]] and [[PAL]] TV norms call for a compliant TV screen to display an electrically black and white signal (minimal color saturation) at a color temperature of 6500&nbsp;K. On many consumer-grade televisions, there is a very noticeable deviation from this requirement. However, higher-end consumer-grade televisions can have their color temperatures adjusted to 6500&nbsp;K by using a preprogrammed setting or a custom calibration. Current versions of [[ATSC (standards)|ATSC]] explicitly call for the color temperature data to be included in the data stream, but old versions of ATSC allowed this data to be omitted. In this case, current versions of ATSC cite default colorimetry standards depending on the format. Both of the cited standards specify a 6500&nbsp;K color temperature.

Most video and digital still cameras can adjust for color temperature by zooming into a white or neutral colored object and setting the manual "white balance" (telling the camera that "this object is white"); the camera then shows true white as white and adjusts all the other colors accordingly. White-balancing is necessary especially when indoors under fluorescent lighting and when moving the camera from one lighting situation to another. Most cameras also have an automatic white balance function that attempts to determine the color of the light and correct accordingly. While these settings were once unreliable, they are much improved in today's digital cameras and produce an accurate white balance in a wide variety of lighting situations.

However, in [[NTSC-J]] and [[NTSC-C]] standards, 9300 K color temperature is recommended. TVs and projectors sold in Japan, South Korea, China, Hong Kong, Taiwan and Philippines are usually adopt 9300 K as default settings. But for compatibility reasons, [[computer monitor]]s sold in these country/region are usually adopt 6500 K as default settings; these color temperature settings are usually tuneable in [[on-screen display|OSD]] menu.
