The perspective used to witness a situation will determine the feelings for what is happening. It works just like how depending on how the lights hit an object they will also appear differently. This green grass appears to be a red, purple and pink combination and it is just because of the lights. The sky does not even look blue and it is all because of the time during which this picture was made. Therefore: next time you realize that you are in a difficult situation, ask yourself if you would react the same if the lights were placed differently.
