“Mired”
Any given change in color temperature produces a greater difference in color at low
color temperatures than it would at higher color temperatures. For example, at a color
temperature of 6000 K, a change of 100 K produces almost no change in color, while a
change of the same amount at 3000 K would produce a large difference in color. Mired,
calculated by multiplying the inverse of the color temperature by 10
6
, is a measure of
color temperature that takes such variation into account, and as such is the unit used in
color-temperature compensation filters.
