Because some minerals have either multiple colors or their color may have faded away over the years
however many light colored minerals can be discoverd by small amount of impurities
it can be white or gray but the word is STREAK
How magnetism can be useful for identifying minerals
there are a few : hardness, luster, cleavage, streak, color, and density. there are more but i don't know them off the top of my head.
thanks it was helpful
A streak test can be helpful identifying any minerals!
color
because many minerals are the same color, and some minerals come in many colors
Color
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.
The properties in identifying minerals are color,luster,hardness,cleavage and fracture,and streak.
It's referred to as the streak, the color of which is used as an identifying characteristic of minerals.

gold and fools gold is the same color. Also for the color blind this would cause problems. So colors can be alike in diffrent minerals or minerals could have a natrual dye on them making color seem diffrent.
Color is probably one of the least reliable properties used in mineral identification. There are many minerals which have the same color, and many minerals have more than one color. For example, hornblende, axi...
which of the following properties is generally the least useful in identifying minerals
The least effective property used to identify most minerals would be the color. The color of a mineral can be altered by impurities.
