I think we can dispense with “seeing with the eyes” since that’s obviously not what mean.

Forming a mental picture, well that seems to be a problem for you. That’s not the “actual” thing.

I don’t think you mean meeting a bet, as in poker.

I can’t figure out what definition of “see” you are using. Maybe the problem is “actual”. If my eyes/mind are reacting to a wave is the wave the actual thing? Are you talking about perceiving all the physics involved in seeing color? What are you talking about?
