What is value in arts?

The term value when used in connection with a piece of art means the tonal value. There is a range between black and white that artists use to create a representation of the idea. Some art work is very dark in value and this conveys a certain mood, just as art that is very light conveys the opposite. Value can also refer to the monetary value of a piece of art. One more consideration is the value of the arts in a society.
