Because weathered surfaces may hide the color of minerals.
Streak
Minerals have certain properties, or characteristics, that help to identify them. Minerals can be identified by their color, luster, streak, cleavage, hardness, specific gravity, and even by their chemical composition.
Physical mineralogy is the specific focus on physical attributes of minerals. Description of physical attributes is the simplest way to identify, classify, and categorize minerals, and they include:crystal structurecrystal habittwinningcleavagelusterdiaphaneitycolorstreakhardnessspecific gravity

because the color of a mineral can be the same as some other minerals but all minerals have a different property between them
Luster is not a good property for identifying minerals because many minerals look similar. Your best way of knowing which mineral is which is by measuring their hardness.
A streak test is used to determine a minerals streak color. This can help in the identification of minerals.
Any one property can be shared by several minerals.
Simply because colour has nothing to do with any other property of the substance in question.
There really isn't one single property, there are multiple properties that need to be used to diagnose a mineral.
It is the streak property. The streak is the color of a mineral in powdered form.
