| Abstract: | This study seeks to assess the potential use of the CIEDE2000 color difference equation in wood science. Therefore, a set of oak wood samples were prepared and assessed by experts. The visual perception of the observers was correlated with the two different color difference equations CIELAB from DIN 6174 and the CIEDE2000 equation. For a practical example two different types of wood were bleached and exposed to UV-light. The results showed that the CIEDE2000 equation outperformed the CIELAB equation. The CIELAB equation showed generally an overestimation of the color change (ΔE) for wood applications, compared to the nontrivial CIEDE2000 equation from 2001. |
