A laboratory human factors experiment was conducted to understand the color rendering properties of various LED-based reading lights. Human subjects rated their preference for a given scene illuminated by a test light source compared to an identical scene illuminated by a reference light source. In another experiment the same subjects viewed and rated the scenes individually when illuminated by a test light source. LED-based light sources were preferred more than halogen and incandescent light… 
An experiment on the color rendering of different light sources
TLDR
An experiment performed by human observers concerning the appearance preservation of color under some light sources, comparing it with a range of available color rendering indices is described.
Psychophysical evaluations of various color rendering from LED-based architectural lighting
TLDR
This research investigated the hypothesis that a significant range of color distortions would be unnoticeable under such dynamically controlled illumination, especially outside of users' main field of view, and confirmed the fundamental hypothesis.
Optimization of LED‐based light blendings for object presentation
TLDR
Light-emitting diode (LED)-based lighting systems seem to have considerable potential for use in shops and display units, where they may well outperform existing lighting systems.
Experimental assessment of color-rendering indices and color appearance under varying setups
TLDR
The open issues related to CRI are presented and some of the approaches available in literature are discussed and an experiment performed with human observers to assess the appearance preservation of a color under a set of light sources is presented.

A source of illumination with good color properties, daylight or electric, should reveal a full range of colors, should enable good color discrimination between objects of similar spectral
The Class A Color Designation for Light Sources
TLDR
The proposed “class A color” designation bundles several metrics shown to be predictive of viewer color preferences, and the designation is intuitively obvious to consumers as one connoting a high-quality light source for color.
Progress in characterizing the multidimensional color quality properties of white LED light sources
With the introduction of solid state light sources, the variety in emission spectra is almost unlimited. However, the set of standardized parameters to characterize a white LED light source, such as
LEDs IN LIGHTING WITH TAILORED COLOR QUALITY
TLDR
In this paper, different methods of assessment of color quality of white light are discussed and a general approach to the solution of the color-mixing problem by means of optimization in respect of several color rendition characteristics is considered.
Spectral design considerations for white LED color rendering
TLDR
Multichip and phosphor-type white LED models were analyzed by simulation of their color characteristics and luminous efficacy of radiation, compared with those of conventional light sources for general lighting.
