About frozen waterfalls and the temperature

the way i thought of a black and white drawing, is because say if you run through Victoria park at night, when there is snow everywhere,and not really any people, then it feels as if everything is like a black and white film because its all like dead still and the snow shines on everything but then the sky is black, so in the end, everything is very bright and black and white, like a shiney photograph from when people used to hold a photograph in their hands.
