• "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, a change

of

1000 K

produces a

much

greater change in

color

at 3000 K

than

at

6000

K.

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.

E.g.:

• 4000 K-3000 K

(a

difference

of

1000 K)=83 mired

• 7000 K-6000 K

(a

difference

of

1000 K)=24 mired
