The mind then transforms what is sensed into a sensation. The sense of red is what the body gives you, the sensation of red is what the mind transforms that into. Our mind also can recall past sensations of red to compare it with and give it a name "red", which a real person can identify as eg a red traffic light and stop. A zombie would not stop (I am not allowing the fact that red and green lights are in different positions). That would be a test of zombieness.
Interestingly, my father began to drive in 1926 in Texas. He was red-green color blind, and he couldn't tell a red traffic light from a green one. And in those days there was no convention as to the order of the lights and there were no yellow lights. So he had to be very careful approaching any signal light. Of course he soon memorized the position of the red and green lights in the small town where he grew up. Later, I think in the 1940's there became a convention of putting the red lights above the green with the yellow in between. Still later, in the '50's, they standardized the spectrum of lights so that the colors did look different even to red-green color blind people. But through all this, I believe my father was a real person.
