It is important to note that the planks are natural products. Because of climate where trees grow, manufacturing processes, and natural wood characteristics, each plank has its unique color, knots, and grain patterns. Color variation, knots and grain patterns variation are natural variations of the wood and are out of people controlled. These situations are normal and no need to raise concern.
However, some species, caused by natural factors, do have less variation than others. When you are deciding wood species for your home decoration, please take your favors and wood characteristics into considerations.
After installation, we suggest you place rugs in corresponding areas or hanging opaque curtains to avoid directly sunlight and to minimize the color variation.
