There are a couple things that "graders" look for in a piece of lumber. One is the knot holes, if they are large this effects the grade. The other is bark no one wants a board that is all bark. So when you are looking for a strong piece of lumber you want one that has knot holes smaller than a half dollar coin and not all barked up the only bad effect that the bark has is it makes it hard to nail to.
In construction grade staking: blue tops (2x2x6 to 12 inch stakes) mark the level of finish grade; red tops (2x2x6 to 12 inch stakes) mark the level of sub-grade; the color comes from lumber crayons used by the surveyor to ID the stakes by colorizing stake tops;

The grade stamp on dimensional lumber typically includes information such as the grade of the wood (e.g., Select Structural, No. 1, No. 2), the species of the wood, the mill identification number, and the moisture content at the time of drying. It may also indicate compliance with specific standards or codes, such as those set by the American Lumber Standards Committee (ALSC) or the National Forest Products Association (NFPA). This stamp helps ensure the lumber meets certain performance and quality criteria for construction and building applications.
When selecting appearance grade lumber for a construction project, factors to consider include the wood's color, grain pattern, knots, and overall appearance. It is important to choose lumber that meets the desired aesthetic requirements while also considering the structural integrity and cost.
When selecting appearance grade lumber for a woodworking project, consider factors such as the wood species, grain pattern, color consistency, knots, and defects. These factors can affect the overall look and quality of the finished project.
