ASSIST recommends... Light Source Color for Retail Merchandising
Published March 2010
This volume of ASSIST recommends describes the two most common metrics used in the lighting industry to define light source color properties: correlated color temperature (CCT) and color rendering index (CRI). This volume focuses on applying these color metrics in retail merchandising applications.
The first issue provides a background on CCT and CRI, including their advantages and drawbacks, and discusses how they may be augmented for better use in retail merchandising.
The second issue recommends two-metric approaches for specifying light sources to achieve desired color appearance and good color rendering in retail applications.
