Because sometimes more than one mineral have the same colour.
Different minerals can have similar colors, making it challenging to distinguish them. The same mineral can come in various colors due to impurities or variations in its chemical composition. Color can be affected by external factors such as weathering or lighting conditions, leading to inconsistencies in identification.
You could test for the property of hardness by seeing which mineral scratches the other. The mineral that scratches the other is the harder one.

A geologist might use a piece of tile to identify a mineral because the unglazed surface of the tile can serve as an effective tool for performing a streak test. This test involves rubbing the mineral across the tile to observe the color of the streak it leaves behind, which can be a key characteristic for mineral identification. The streak color can differ from the mineral's appearance, providing additional information for accurate classification. This simple method is practical and widely used in fieldwork and laboratory settings.

In some cases it will cost more to mine and refine the mineral than that mineral is worth. This can occur if the concentration of the mineral is too low, or if it is buried too deep to be accessed cost-effectively. In this case, the mineral resource is techincally not an ore, as by definition, an ore is a mineral resource that can be extracted at a profit.
