Fluorite's streak is white because that is the true color of the powdered form of the mineral. The impurities that cause color or tint in a mineral specimen are so insignificant in relation to the true mineral content that they are not visible when powdered.
You can distinguish these minerals by testing their physical properties such as taste (halite is salty), hardness (calcite scratches easily with a knife, halite is soft, fluorite is harder), and fluorescence (fluorite exhibits fluorescence under UV light). Additionally, you can use a hand lens to examine their crystal shapes or conduct a streak test to observe their powder color.
The color of fluorite changes due to the presence of impurities in its crystal structure. Different impurities can interact with light in various ways, influencing the color of the fluorite. This phenomenon is known as "color zoning" and can result in a wide range of colors in fluorite crystals.
Streak refers to the color of a mineral in powder form.
the color of the streak for dolomite is white
there is no name for the color, but there is the "streak" of a mineral, meaning the color of its streak.

Color is an ambiguous property of fluorite. Fluorite can come in a wide range of colors due to impurities in its composition, so its color alone is not a reliable diagnostic characteristic. Other properties, such as cleavage and fluorescence, are better for identifying fluorite.
Pyrite
the streak color is Dark Green
Perlite does not have a streak color because it is a volcanic glass that does not leave a streak on a streak plate.
the color is purple pink and tan
