Exactly. But you have to understand why Spacemonkey. You're not getting it yet, so it sounds crazy because the light hasn't reached the eyes ACCORDING TO THE AFFERENT MODEL OF SIGHT.

But this is exactly what I was describing as instantaneous teleportation of duplicate light before, and you denied that was what happens. (On this model, the light at the surface of the object is constantly creating and updating duplicate copies of itself at the film or retina.)
Imagine the Sun is ignited, but comes into existence alternating between yellow and green every second. When it first ignites, it is yellow, and yellow light comes into existence at the observer's eyes. So there is yellow light at the observer's eyes and at the Sun. One second later, what color is the light in the observer's eyes? Is this light the same light that was there just before, but with a new color (frequency)? Or is there new light constantly coming into existence in the observer's eyes, matching the real-time color of the Sun? And where is the yellow light which was at the Sun a second ago? Is any of it travelling towards the observer at this point?
