Philosophical projectionism

What is philosophical projectionism?
Projectionism is the theory (my theory) that perceived objects have not qualities as such but that qualities are projected onto them by the perceiver. This naturally means an object can have as many projections upon it as there are perceivers of it. The object does not “change” in any way, and it is not directly affected it by the perception of it. Objects remain the same whether perceived or not. Qualities therefore do not exist accept for within perception. Projections are concepts. They are conceptualised. The end of all conceptualisation is the end of the concept, but not the end of the object.
