A spectrophotometer is a critical instrument for measuring color stability. It measures the absorbance or transmittance of light at different wavelengths, providing objective data on the color characteristics of the sample.

The CIELAB color space is often used to quantify color changes. This system defines color using three parameters:

L*: Lightness (0 = black, 100 = white)
a*: Red-green coordinate (+a* = red, -a* = green)
b*: Yellow-blue coordinate (+b* = yellow, -b* = blue)

The total color difference, denoted as ΔE, is calculated using the following formula:

ΔE = √((ΔL*)² + (Δa*)² + (Δb*)²)

This value represents the overall color change between the initial and subsequent measurements.
The storage conditions, such as temperature, light exposure, and humidity, are carefully controlled. For instance, samples might be stored at different temperatures (e.g., 4°C, 25°C, and 37°C) and exposed to varying levels of light. The color measurements are taken at regular intervals (e.g., daily, weekly, or monthly) to track the changes in the color parameters.
