Abstract
Colorimetric measurements are often carried out for evaluation of colour changes on wooden surfaces. However, a grading of the value \(\Delta E^{*}_{\mathrm{ab}}\), (colour difference) is missing for wooden surfaces.
Colour measurements were carried out on surfaces of six wood species. It could be shown that there is a native colour difference within wooden surfaces which is influenced by the texture of the wood. This native colour difference has a magnitude of \(\Delta E^{*}_{\mathrm{ab}}\) of about 2.
