Colored leads typically come in the above eight colors. Pencil leads are made from a mixture of pigments and binders. Where standard pencil leads use graphite as the pigment to get its distinctive gray color, colored pencil leads use colored pigments to create a variety of hues.
What is the hardness of pencil lead?
The familiar ‘graylead’ pencil has a graphite/clay core encased in cedar wood. These range in hardness from around 9b (very soft) up to 9H (very hard indeed) depending on the brand.
