The pigment bit in the colored pencil has a waxy base that will build up and jam/get stuck in the sharpener. Graphite doesn’t. It can be used as a lubricant in some non sexy situations.
The “lead” is often softer and prone to breaking off, leaving a little cone of lead plugging the end of the sharpener needing to be cleared out by opening it up. A pencil sharpener for coloured pencils sharpens at a steeper angle for this reason
Seriously though, is there any reason to disallow colored pencils in a pencil sharpener? I can’t think of any problem they might cause.
