no, because the same mineral can be more than one color.
Hardness and streak color are very important. The color of the mineral helps some, as well.
Its considered an ore when it contains enough of a useful substance that it can be sold
Streak tests are used to identify minerals. Rubbing a mineral specimen against unglazed white porcelain, or finely powdering it and examining the powder against a white background, is a useful diagnostic test in some cases. Eg. hematite, a black mineral that looks much like many other black minerals, has a distinctive red streak.

This is a raw material (feedstock).
Luster is typically considered the least useful mineral property, as it does not provide much information about the mineral's identity or composition. Luster simply describes how light is reflected off the surface of a mineral, such as metallic, glassy, or dull, and can vary even within the same mineral species.
The color, luster, and crystal shape of a mineral may be observed just by looking at the mineral. Some minerals have very distinctive colors that help identify them. Although the color of a mineral can give away its identity, color is the least useful property for mineral identification.
you see and feel how shiney it is
The color of a mineral is the least useful when identifying minerals. A mineral can exist in various colors. This is because presence of certain chemicals will change the color of the mineral. Weathering can also change the color of the mineral. Therefore color is not a good property to identify minerals.
Density is the least useful property for identification because different specimens of the same type of mineral can vary in size. -Color is the least useful property for identification because it is the most obvious property.
Other mineral properties such as luster, streak, and specific gravity are less useful for identification because they can vary widely among different minerals and may not be unique to a specific mineral. In contrast, properties like hardness and cleavage are more consistent and can help accurately identify a mineral.
For example the melting point.
The most useful physical property when classifying a rock is its mineral composition. This includes identifying the specific minerals present in the rock and their relative proportions. By analyzing these properties, geologists can categorize rocks into different types based on their mineral content.
Density is a physical property that can help identify minerals because different minerals have unique densities. By comparing an unknown mineral's density to the known densities of common minerals, geologists can narrow down the possibilities for identification. This is especially useful when other identifying characteristics are not easily observable.
Knowing the specific gravity of a mineral can help in mineral identification because it is a unique physical property that can distinguish between different minerals. It can also provide information on the composition and density of the mineral, which can be useful for various scientific and industrial applications.
The property of cleavage or fracture would be most useful in identifying the unknown rock. Cleavage refers to the way a mineral breaks along flat surfaces, while fracture refers to how it breaks when no cleavage is present. These properties can help to determine the mineral composition of the rock.
In classifying rocks, there are many properties that can be useful. In my opinion, either color or texture is most useful in classifying a rock or mineral.
