Firstly, from a historical perspective, the sequence of events that led to the formation of the the imaginary red Ferrari did not come about without reference to the material object (the light hit the object, which came to your eyes, was processed into signals that led to your brain--all of these are different)--so it appears you are already on the wrong track. And the fact that your mental picture of the object is different from the actual object does not prove that the two objects are in "separate realities." The picture (an object) of the Ferrari on your screen is a separate thing from the actual object, but BOTH the picture of the object AND the object itself exist in the same "world" framework. Just because they are different doesn't mean they are completely separate and independently founded realities.
Your illustration is fine, its just incomplete. What you fail to mention are the background details that connect the reality of the car to your "mental image"
(1) Your recognition of the car was not based on any rules that you explicitly followed -- you just did it
(2) If I asked you how you recognized the car, you would give me a story (a story that your body and brain DID NOT USE IN ITS RECOGNITION!)
(3) The referential totality of things related to cars, wheels, driving, car body shops, engines, equipment, and all other stuff that formed the background of intelligibility of the same-- without this background of other relations between yourself and these things, you would have no "image" of a car--what you would have is an image of a big large shiny red blob with black blobs and clear translucent panes ....etc .etc
(4) Your relation to the car; to the car's equipmental totality; to the car's driver; to the place it is photographed; i.e... an innumerable other relations is precisely what is constitutive of your seeing it as such--this blows the "separate realities" thesis right out of the sky. They are part of the same reality--they may be DIFFERENT...but DIFFERENT objects in the SAME REALITY is not the same as them being separate and independent sources of reality which is what a dualistic perspective would claim.
