Suppose a person sees a guy wearung red Tshirt and a pink trouser. At a first glance he disliked that combination of outfit, while another person beside him liked the combination. So why did this difference in perception of colour emerged even though they were looking at the same thing at the same condition? Is it because of their differences in upbringing? Or is it due to violation of uniformity of one's perception (I mean a person is more familiar with a combination of red and blue but when he saw the red-pink combo which is completely unfamiliar to him, he just could not take it because of asymmetry)?
Again someone likes to have meat and he eats it quite rarely. But he dislikes milk. Even he drinks milk everyday or rarely, he dislikes it. On the other hand even of he eats meat everyday he does not dislike that as he does dislike milk. Why does that happen? Is it something related to composition of milk and meat which involves chemistry to understand or is it completely a psychological topic?
