Quartz is the only one mineral in which leaves a colorless streak
The mineral Quartz leaves a colorless streak.
biotite has a colorless streak
a sapphire doesn't have a streak.
The streak of pink quartz, like that of other varieties of quartz, is typically colorless or white. Streak refers to the color of the powder produced when a mineral is scraped across a hard surface. While the external color of pink quartz may vary, its streak remains consistent due to its mineral composition. This characteristic helps in identifying quartz and distinguishing it from other minerals.
A ruby's streak color appears colorless because as a mineral, ruby typically does not leave a streak when rubbed against a streak plate. The color of a mineral's streak is caused by the powdered form of the mineral, revealing its true color when scratched against a ceramic plate, but in the case of ruby, its hardness and structure prevent it from leaving a visible streak.
The streak of an opal is typically colorless due to its amorphous structure. It doesn't leave a visible streak on a streak plate like some other minerals do.

The streak for a diamond is colorless.
One common test to distinguish between nonmetallic and metallic minerals is the streak test. Nonmetallic minerals will typically leave a powder streak of color when rubbed against a white ceramic plate, while metallic minerals will leave a metallic streak.
Whitish-gray stones with a nonmetallic luster that leave a colorless streak are likely to be varieties of minerals such as quartz or feldspar. These minerals often exhibit a light color and can be found in many geological environments. Their nonmetallic luster and ability to leave a colorless streak are characteristic features used to identify them in mineralogy. Further examination, including hardness and crystal structure, would help in precise identification.
Tourmaline crystals can have a streak that ranges from white to colorless. The streak of a tourmaline mineral is usually lighter than its external color.
It is colorless.
Two minerals that do not leave a streak on a streak plate are quartz and fluorite. Both minerals have a hardness higher than that of the streak plate, so they will not leave a streak when rubbed against it.

Some colors are light gray, pinkish, redish. Glad to help.
