A good answer might be:

There is nothing wrong with the program. Since color is a primitive data type, an expression such as

color == 'V'

compares the contents of color (a character) to the character literal 'V'. However, the following would be wrong:

color == "V"

This is asking to compare the character value in color with a reference to the String object "V".
