Post 1 Simultaneous Contrast

When I first saw the two squares in the simultaneous contrast example in the book I went along with what everyone sees and later realized that both of the squares were the same size. I then thought to myself, how does this apply to real life? After thinking about it I realized that these sort of illusions happen to us all the time. N-Wing was the first example that came to mind. When we look at the food under the lights they look delicious and then when we take it to our table it looks disgusting. In all actuality it is the exact same food but we perceive it differently depending on the background or lighting. When the food is under the light they send a larger amount of inhibition than when they are not under that heat lamp, therefore showing us that the food looks more appealing under the light than without that light.
