In some cases, the paprika is being used primarily to add color to a dish, in which case you could add a small amount of some other red ingredient, which could be anything from a teaspoon of ketchup with a dash of chili powder mix to tomato sauce, finely pureed red peppers, tomato paste, or red beet powder. If you have bell pepper powder, use a 2:1 ratio, as the bell peppers are very sweet and don't have the kick of sweet paprika.
