Hardwood flooring is organic and inherently reactive to environmental conditions. Oxidation is the chemical reaction between oxygen and the compounds in the wood, accelerated by UV rays from sunlight. Species like cherry and mahogany tend to darken significantly, while others, like oak or maple, may exhibit subtle ambering or yellowing over time. This is a natural aging process and not a manufacturing defect. The degree of change depends on the intensity of light exposure, the finish used, and the wood species. Consistent sunlight exposure can also cause uneven coloring if areas are covered by rugs or furniture.

What causes color variation in aging hardwood?
Color variation in aging hardwood is primarily caused by exposure to ultraviolet (UV) light, which triggers oxidation within the wood's cellular structure. This process leads to either darkening or lightening of the timber's pigments, depending on the specific species of the wood floor.
