Paolo was measuring the streak of the mineral. The streak is the color of the powder that a mineral leaves when it is scraped across a hard surface, such as a tile. This property can help identify the mineral, as the streak color may differ from the mineral's external color.
No. It can vary from the visible color of the mineral and, since visible color of them ineral is not a reliable indicator of type, it is important to learn to use streak, (along with other factors), to correctly identify a mineral.
no, because the same mineral can be more than one color.
Hardness and streak color are very important. The color of the mineral helps some, as well.
then a mark is left on a mineral and is presentable!
The color of the mark left when a mineral sample is rubbed on a harder surface is called the streak color. It can sometimes differ from the color of the mineral itself, providing important clues for identification.

Streak. The 6 properties of minerals are streak, hardness, crystal form, color, cleavage/fracture, and luster. Hope that can answer your question:)
A mineral's streak is the color of the powdered form of the mineral, which is consistent regardless of variations in the mineral's surface color. This makes streak a more reliable identification tool than the mineral's exterior color, which can be influenced by impurities or variations.

It's just the mineral's natural color.
The mineral that makes the color blue in gemstones is typically caused by trace amounts of elements like copper or cobalt. These elements absorb certain wavelengths of light, giving the gem its blue hue. Examples include blue sapphires with traces of iron and titanium, and turquoise with copper content.
The streak of the mineral is the mineral's powder color
The color of a mineral's powder found by scratching the mineral on a white tile is referred to as the mineral's streak color.
Streak is the color of a crushed mineral's powder. The color of a mineral's powder may differ from the actual color of the mineral. This property can be useful for mineral identification.Almost every mineral has an inherent streak color, no matter what color the actual mineral is.
Graphite is the soft mineral often used in pencils. It is a form of carbon that leaves a gray mark when used for writing or drawing.
