Once again, I'm not arguing against usefulness. Our sensory mechanisms are designed to convince us that the car is yellow. Since it's not (the yellowness is added by our sensory mechanisms in such a manner as to make us think the car is yellow) we can speak factually concerning our lyin eyes.
The yellow cab is yellow. And by "yellow" we mean the color we perceive trough our sensory mechanisms (eyes and brain) as yellow. That's the label we put for a visual property of light that is reflecting from the cab.
A bee might perceive the yellow cab as purple (and by "purple" I mean the color we perceive trough our sensory mechanisms as purple).
That doesn't mean that saying: the yellow cab is yellow, is a lie (or not true). Or that our eyes are lying.
In the context of the ideas proffered in the early part of this thread, the issue concerns the basis of what we believe to be true. The same sensory mechanisms that tell us a particular electromagnetic vibration is yellow, tell us the sun and the moon are the same size. And just as the sun and the moon are not the same size, the electromagnetic vibrations aren't yellow.
It's recognition that our sensory mechanisms are serving nature, natural selection, and not necessarily God, or a more fundamental knowledge of truth, that led the ancient religious priests (the first scientists) to begin to fight back against nature and the body nature designed to keep us in the dark, and nature on the throne.
The Copernican Revolution is an exaggerated example of the foregoing. When Copernicus told the world that it wasn't the center of the universe, nor even the center of the solar system, the corrupt priests and armchair scientists couldn't believe that their eyes and sensory perceptions would tell them such a giant fib.
