Simply because colour has nothing to do with any other property of the substance in question.
Streak is the property of a mineral that is determined by rubbing the mineral on a special plate to reveal the color of its powdered form. This can help identify minerals because a mineral's streak color is often different from its external color.
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.
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.
Color can vary within the same mineral due to impurities or environmental factors. Additionally, many minerals come in a variety of colors, making it difficult to identify them based on color alone. Therefore, color is often not a definitive property for identifying minerals.
Color is not always a reliable property to identify a mineral because many minerals can come in various colors or shades due to impurities or environmental factors. This can lead to confusion and misidentification. Other physical properties, such as hardness, streak, cleavage, and luster, are more reliable indicators of a mineral's identity.
because the color of a mineral can be the same as some other minerals but all minerals have a different property between them
Streak is the property of a mineral that is determined by rubbing the mineral on a special plate to reveal the color of its powdered form. This can help identify minerals because a mineral's streak color is often different from its external color.
Color is the least reliable property to use to identify a mineral because many minerals can occur in various colors due to impurities in the crystal structure.
Color is an unreliable property to identify minerals because different minerals can have the same or similar colors, leading to confusion. It is better to rely on more definitive properties like hardness, cleavage, luster, and streak for mineral identification.
A streak test is used to determine a minerals streak color. This can help in the identification of minerals.

StreakColor of the mineral when it is powdered.Grind a small amount of a mineral into a powder on a porcelain streak plate and determine the color of the powder.
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.
Color can change in a mineral when in certain temperatures
Color can vary within the same mineral due to impurities or environmental factors. Additionally, many minerals come in a variety of colors, making it difficult to identify them based on color alone. Therefore, color is often not a definitive property for identifying minerals.
