Let's make that ground red pepper and ground cayenne pepper, OK?

It's like the difference between fruit and apples. Apples are a kind of
fruit, but if you have a piece of fruit, it isn't necessarily an apple, it
might be an orange, banana or even durian.

Ground cayenne pepper is a kind of ground red pepper, but if you have some
ground red pepper, it could be any kind of ground dried red pepper,
including some that are quite mild.
