In philosophy of mind, what is the difference supposed to be between a quale and a representation?

A quale is a sensation that does not have conditions of satisfaction, i.e. there is no way the world must for that sensation to be appropriate.

A representation has conditions of satisfaction.

Some representations, e.g. sense-perceptions, are mediated by quale, whereas others, e.g. thoughts, are not.

But even though quale sometimes mediate representations, they are never all there is to a representation. This is because a quale cannot have conditions of satisfaction unless accompanied by mentation that extracts meaning from that quale.

The quale that compose a visual perception would be so many non-representational blotches were they not intermingled with ideation that constantly assigned meaning to them.
