Name: Chromaticity Tolerance
Assigned Number: 0x0007
This property represents the tolerance as a circle in the CIE 1976 (u',v') diagram of the chromaticity of the light produced by a device, such as a light source or a lighting fixture . This tolerance can, for example, be dependent on the current setting, temperature, or operating history of the device. It can be used to decide when to replace a light in quality-sensitive lighting applications.
