What does the spectrum of pencil types range from?

The spectrum of pencil types is categorized based on the hardness or softness of the graphite used in their manufacture. The grading scale ranges from "H" for hard pencils to "B" for soft pencils. "F" stands for fine point, but it's less commonly discussed.

The correct answer highlights that the spectrum runs from "B" to "H." Pencils marked with "B" are softer and produce darker lines, which are suitable for shading and artistic work, while those marked with "H" are harder, producing lighter lines that are often used for finer details and technical drawing. The grading system helps artists and designers choose the right pencil for their specific needs, balancing between darkness and precision.

The range effectively showcases a transition from softer to harder materials, emphasizing the varying uses of each pencil type in different contexts, such as sketching, shading, or fine detail work.
