Since white is a combination of all colours and no other colours are allowed then technically white should not be allowed either :O) But then black and white are the same colour. They have the same Hue and Saturation the only difference between them is the amount of light. So... White is all colours and black is the same as white. Which means that you cannot make an image out of shades of grey without using other colours! ;O)
