They appear in a “perceptual semantics” that Bell (the logician, not the physicist) has proposed for a special quantum logic. They belong to the logic of the material modes of the self (defined with a mathematical apparatus G*, often called logic of self-reference) in the communicable part. It shows that a s-certain type of machine will be able to describes what it sees, name colours, and be able to understand that their qualia seems not rationally communicable. The machine might see the red coloration more like a “green” perhaps, but of course, she will learn to call it green. You need to read some book in logic to grasp fully what G* is all about. But that is the answer in a nutshell.
