Fig. 1-6A The lines of
correlated color
temperature and their
relationship to the
blackbody curve are seen
in this illustration. The lines
of CCT run roughly
perpendicular to the
blackbody from
green/yellow to
orange/violet. Take note
that all the colors along a
line of CCT can be labeled
with the same color
temperature. The colors
marked “e” and “f” in the
diagram may both be
described as 5000 K.

Fig. 1-6B This screen
capture from the Sony
Artisan display software
illustrates a close-up of the
blackbody curve and above
it, what is known as the
daylight curve. Here the
standard illuminants are
plotted. The spectra of the
D illuminants can be
converted to xy and
plotted on the CIE
Chromaticity diagram as
this daylight curve.
