Color Considerations

The appearance of color, both in terms of chromaticity (color temperature or kelvin) and color rendition (CRI) are important in the overall feeling of a space, and in some instances can have a dramatic effect on visual tasks. The designer should consider both chromaticity and CRI as key components of a design. This section describes these parameters of color, and provides insights into their use.

Chromaticity 
Color temperature preference is rather subjective, although most commercial illuminants fall within the range of 3000K to 4500K and lie along the black body locus or curve.

Color Rendering 
Color quality is generally assessed using Color Rendering Index (CRI), a scale having a maximum rating of 100 for reference sources like daylight and standardized incandescent light.
