What property might be more useful to tell two materials apart their mass their temperature or their color?

Color is often the most useful property for distinguishing between two materials, as it can be a readily observable characteristic that varies significantly among different substances. However, mass can also be informative, especially when considering density, which can help identify materials with similar colors. Temperature is typically less reliable for identification, as many materials can exist at similar temperatures. Ultimately, the effectiveness of each property depends on the specific materials being compared.
