A terminal, a color changing method, and a color changing apparatus that relate to the field of communications technologies are provided, so as to resolve a technical problem of a waste of materials due to production of a terminal shell. A color changing unit is disposed inside a terminal, where the color changing unit can change a color when receiving electrical energy, and a transparency value of a shell is greater than a first preset transparency value, so that a technical problem of a waste of materials due to production of a terminal shell can be effectively resolved, which can reduce manufacturing materials and is conducive to environmental protection.
