The item description says "black" for the colour. However, the pictures do not give me the impression that the entire keyboard is black, but rather grey or graphite. Before I buy this keyboard and mouse, I would like to make sure that the entire keyboard really is black or not. I know that the keyboard is also available in completely black, as I have watched various videos. I know that the small bar above the keyboard (where the logi logo is) is black. But I would like to know if the rest is also black. Thank you for your answers.
