Relation of Chemical Composition and Colour of Spruce Wood [PDF]
Polymers, 2022 The visual inspection of fresh cut spruce wood (Picea abies, L. Karst.) showed the variability of its colour. Wood visual inspection is a part of wood quality assessment, for example, prior to or after its processing. The detail spruce wood colour analysis was performed using spectrophotometric data.

Wood colour of radiata pine [PDF]
, 2005 The colour of the wood in radiata pine has large variations due to natural factors and also wood processing treatments. Wood colour has been previously studied in many wood-related processing areas, such as pulp and paper, coating, photoyellowing and veneering, while few studies have been done on the colour of fresh, green wood.

Colour Changes of Weathered Wood Surfaces Before and After Treatment with Iron (II) Sulphate [PDF]
Drvna IndustrijaOutdoor wood is exposed to various factors that can be described as weathering and cause the wood to grey. The ageing processes can vary greatly depending on the exposure. Parts of wood that are not exposed to external factors, e.g. under the overhanging,

Colour Stability of Thermally Modified Wood during Short-Term Photodegradation [PDF]
BioResources, 2014 Dry thermal treatments of wood samples were carried out at 160 and 200 °C. After each treatment, the samples were irradiated using a strong UV emitter mercury lamp, and the colour change was then evaluated.

Wood colour related to kiln drying [PDF]
, 2000 Raised temperature in artificial drying has led to some changes of wood products such as colour and strength etc. For special treatment of wood-products with clearly modified properties, among them colour, is often high temperature and steam used industrially.
