Can give color to the silence ?

The first time I believe that silence is golden , because I think the silence I don't waste my time with something that I think is not important .
Let me know the situation with silence , a silence I can feel , I can tell all their eyes , blank stares and stares of hatres .
But when I couldn't tell it by way of silent stares , I prefer to close my eyes and I see only black and full of darkness .
So what can I say silence is black ?
Well , silence is black . 
Silent when they feel emotion , angry , and hate .
