Birch is a smooth, even grained hardwood that is predominantly off-white with some red and brown variation giving it a calico appearance. Birch cabinets with a wiping stain will not be consistent in color. The ends of the stiles and the cross grain profile in the raised panel will be much darker than the rest of the door. In addition, the face frame, doors, and drawer fronts can vary in color. This is not considered a defect but desired by those wanting a "rustic" look.
