The Walnut wood color will vary based on how the wood was dried. Kiln dried lumber that has been heat treated to efficiently speed up the drying process will result in a flat brown color. However, if the wood is allowed to air dry, then a dark purplish color is created that is very unique and works well in decorative uses. Walnut is typically too expensive to reasonably be used to construct kitchen cabinets, but veneers can be used to give the appearance without the overwhelming cost. Walnut can also be very useful as kitchen highlights since many products are made from walnut. It is a wonderful wood to use for embellishments like corbels and baseboards.
