I think B&W is definitely either at the bottom or increasing. A company like Ilford is NOT supplying the ordinary consumer. This is already a virtually 100% specialist hobbyist market. If Ilford can make it work for B&W then possibly another small company can do the same for colour. Or perhaps if Kodak do disappear Ilford might run a couple of colour products. They already have a chromogenic B&W so I am sure they could run colour if they wanted to.
