Uncertainty Estimation in Colour Measurement: An In-Depth Analysis

Colour measurement is crucial in diverse scientific and industrial applications where accurate estimates of associated uncertainties are essential. The work of J. L. Gardner, published in Color Research and Application, provides a comprehensive framework for estimating uncertainties in colour measurements. This article examines the challenges and methodologies involved in quantifying these uncertainties within colour science.

Introduction to Uncertainty Estimation in Colour Measurement

In scientific disciplines, measuring uncertainty is fundamental to the reliability of data. Gardner emphasises the importance of international standards such as the ISO Guide to the Expression of Uncertainty in Measurement. This standard provides a structured approach to quantifying uncertainties, although the examples are not specifically tailored to colour measurement.

The concept of measurement uncertainty is crucial for determining how reliable and consistent a measurement process is. In practice, colour measurement is widely used in display manufacturing and the paint industry. Because colour depends on lighting conditions and the observer, estimating uncertainties is complex. Gardner demonstrates that measuring colour variables without a notion of uncertainties is incomplete, especially when the data must meet certain requirements.
