it can be white or gray but the word is STREAK
Color is what you observe when you look at a mineral. Streak is the color of the mineral when in a fine powder form. This can be observed by drawing a sample of the mineral over an unglazed porcelain tile and noting the color of the line left on the tile.
The color of the powder left on the rough surface by a mineral is called its streak. The streak plate is a hard surface that helps to determine the different shades and characteristics of the minerals that is rubbed on it.
Color is not a good identifier of minerals.
Because some minerals have either multiple colors or their color may have faded away over the years
Pigment is a powder typically made from crushed rock or minerals and is used for coloring various materials or surfaces like paint, ink, or cosmetics. These pigments can vary in color, texture, and composition depending on the source material.

It's called the minerals streak
No, the streak is the color of a mineral when it is crushed to a powder form and pulled across an unglazed porcelain plate. This helps in identifying minerals as some minerals have different colors on their streak compared to their natural color.
i believe different grades of gun powder
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 streak test can only identify minerals that have a consistent powder color when scratched on a rough surface. It may not work well for minerals harder than the streak plate or those with a variable powder color due to impurities. Additionally, some minerals lack a distinguishable streak color, making it unreliable for their identification.
Different powdered minerals have different colors. Yellow minerals include millerite and colusite. Blue minerals include aubertite and borax. Green minerals include zircon and duggenite. Reds include cuprite and spiroffite. Minerals come in many different shades.
Different minerals have different colors, actually.
The color of a mineral's powder is its streak. This is the color of the powdered form of the mineral when it is scraped against a hard surface. Streak is a more reliable indicator of a mineral's identity than its exterior color.
