Black its not just a colour its an emotion.
Blank it means nothing.but there is something behind that.well everyone have their own problems in their life.in that situation either we should face it or or we should quit.every problem has solution but we should try to solve it.problems will try to test our strength and patience.people who r strong they will face it.and rest will quit.well whenever u try to quit from ur problem ur life will be blank.and if you try to solve ur problem ur life will be black.well something is better than nothing.if u try to solve,atleast your life will be black but if you don't try your life will be blank.and definitely there is something behind that blank but it won't worth.overall it depends on you to choose either black or blank.
