Color Rendering Capacity of Light The Color Rendering Capacity is one of several measures of the color rendering quality of light sources, specially devised to tackle the question of how many colors on earth can be vividly rendered by a given kind of light sources? or how to know whether a given kind of light sources is capable of rendering a great number of widely different colors? The calculated color rendering capacity is a figure proportional to the upper limit for the number of the object colors producible under the light source of given spectral power distribution with one unit luminous flux, i.e. proportional to the volume of the color solid associated with the light source of given spectral power distribution. A free software CRC99 for calculating the color rendering capacity of any light source has been available. Reference: Xu He, Color Rendering Capacity of Light, 2010, Amazon. Calculation Software: http://www.host-a.net/u/colorrendering/Crc99.zip (a simplified version, Crc99.zip,18KB). Note: Download the file to drive c:\, and unzip the file to folder c:\Crc99\, then run c:\Crc99\Crc99.exe, that is all.
