What is the sequence of pencil hardness from boldest to lightest?

The sequence of pencil hardness from boldest to lightest is important for understanding the variety and application of pencils in drawing, writing, and technical work. The grading system for pencil hardness ranges from softer, thicker marks (B grades) to harder, finer marks (H grades).

In the correct option, which starts with 6B, this represents the boldest or softest pencil type, producing the darkest marks. The designation "B" stands for Black, indicating the pencil has a softer lead, making it suitable for darker lines. Following that, 4B is still soft, but slightly harder than 6B, and it produces lighter marks. Next in the sequence is 2H, transitioning into the harder pencil types which produce thinner, lighter lines. Finally, H represents the hardest point on the scale that results in a very light mark.

This sequence demonstrates a clear transition from soft, dark leads used for bold, dramatic shading to harder, light leads suitable for precise and technical work, reinforcing the understanding of how different pencil grades can be used effectively in various contexts.
