Abstract: The CIE CRI has been criticized for its poor correl
ation with the visual
colour rendering of many spiked or narrowband sourc
es, its outdated
colour space and chromatic adaptation transform and
the use of a small
number of non-optimal reflectance samples, which ha
ve enabled lamp
manufacturers to tune the spectrum of a light sourc
e to yield, in some
cases, inappropriately high general CRI values. The
CRI2012 metric
proposed in this paper addresses these criticisms b
y combining the most
state of the art colorimetric colour difference mod
el, i.e. CAM02-UCS, with
a mathematical reflectance set that exhibits a high
ly uniform spectral
sensitivity (to preclude gaming). A set of 210 real
reflectance samples has
also been selected to provide additional informatio
n on the expected colour
shifts when changing illumination.
