If you use expired hair color and the tube is expired the ammonia could be oxidized. If it is it will not react with the peroxide. You may get a stain, but it will not be able to open the hair to deposit it where it needs to go. The dye will hang out outside the hair instead of going inside.

Hydrogen peroxide breaks down the natural melanin pigment in the hair, which also comprises the hair's natural moisture. This chemical reaction often leads to dry, brittle strands. Over time, the loss of moisture can exacerbate hair breakage and split ends, making hair management a tedious task.
The hardest hair colors to remove are typically black and vivid reds, due to their dense pigment load and strong staining power, often requiring multiple bleaching sessions; while vivid blues and purples are also very difficult, especially cool-toned ones, because their small dye molecules deeply bond to porous hair, making them stubborn to lift.
