• "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
