Black Coffee Cup

I like to have a cup of coffee in the morning. I'm having a cup right now as I'm typing this. The black coffee cup I'm drinking is the subject of my latest still life drawing. I was reading where Impressionist Painters rarely ever used the color black in their paintings. I've noticed in those works of art, dark subjects like a night sky or shaded areas are not colored with black. I thought this would be a fun subject matter to tackle. I went ahead and did color my subject matter black. Unlike my last still life drawing entitled STOOL, I did add shading to this drawing by using gray colors. And the coffee I drew is that of a dark brown, although I like to drink it black. I'll be putting the finishing touches on this drawing I call BLACK COFFEE CUP later today.
