The pack is black ( oil-painted canvas, so a slight sheen) with white buff straps. The number 42 was probably painted in white on the back.The waterbottle is mid-blue, not too bright, and the ammo pouch( white buff straps on the underside) and the messtin in its oilcloth cover are also black. Since he appears to be wearing his greatcoat ( grey, correct) the item rolled on the pack must be his blanket , which were at that period buff. In fact they rarely wore their packs in the field since they landed in the Crimea without them, only receiving them some months later, in a thoroughly pillaged state.
