If you don't mind me answering, Sandra-chan, 8B is the darkest pencil. The lighest is like 8H, then 7H, 6H, 5H, etc etc. Then H, and then something else (I forgot), and then HB (the normal pencils we use.) After HB, it's B, then 2B, 3B, 4B, etc etc etc, until 8B, which is the darkest (i'm pretty sure, unless there's a 9B.)
Clear? xP
