What Is it Like to Be a Bat?

Feeling is a relationship between a particular observer and a particular observed.

So the question of “whether the color red I see is the same as the color red you see” is logically meaningless.

If observer B can get the memory of observer A, it is logically possible to feel another mind’s feelings (to a certain extend).

In that situation, the question of “whether B’s feeling of seeing the color red is the same as A’s” is meaningful.
