The darkness of pencil lead is determined by its graphite-to-clay ratio. The higher the graphite content, the darker the lead. Therefore, a pencil lead labeled as "HB" or "B" will be darker than a lead labeled as "H" or "F." The darkest pencil lead commonly available is typically labeled as "6B" or "8B," indicating a high graphite concentration.
