My photosmart 8450 won't print in anything but black. Says it is using back up mode

Even though I bought a new photo cartridge (hp99) and installed it the printer continues to print in back up black mode. It doesn't matter whether it is connected to my Mac or standing alone with a card. Any suggestions
