Color Determination by Spectrophotometer
Instrumental measurements of color and color difference are critical to color identification and color matching. Measurements can be used to compare materials exposed to surface/aging treatments, assess color stability, or compare products from different sources or processes. We have petrographers with substantial training and experience in color theory and measurement.

Visual estimations of color can be made using the ISCC–NBS System of Color Designation and/or the Munsell color system, although color perception varies between observers and lighting conditions.
