A mostly heartwood flooring product that allows all the natural heartwood color variations with minimal character marks and limited color variation. This combination features the infinitely variable grain patterns with the minimal distraction from character marks and color variation.
Contains all the variations in coloration produced by the contrasting differences of heartwood and sapwood. Also included are minimal character marks, such as small knots, worm holes, and mineral streaks, as well as slightly open characters. The combination creates a floor where the light sapwood and dark heartwood are combined with small characters and other small color interruptions.
