In color measurements, what is described as the minimum color difference detectable?

The minimum color difference detectable in color measurements is referred to as sensitivity. Sensitivity is a critical concept in this context, as it pertains to the ability of a system or instrument to detect small variations in color. A high sensitivity means that the system can recognize and measure minor changes in color accurately, which is crucial in applications like quality control, where even slight deviations from a desired color may indicate a problem.

In contrast, precision refers to the reproducibility of measurements, stability relates to the consistency of a measurement system over time, and specificity denotes the ability to measure a particular characteristic without interference from other variables. While all these concepts are important in the realm of measurements, sensitivity specifically focuses on detecting minute differences in color, making it the correct term for describing the minimum color difference detectable.
