There is no single valid answer to this question. A sandstone is defined as a solid rock (no soft sediment) that is mostly composed of mineral grains of diameters between 0.063 and 2 mm. The definition does not include any information on the mineralogy of the rock. As the streak test is sensitive to the type of mineral that one tests, any possible result can be created.
No one knows.
Rocks are not considered to have a streak, as they may consist of several minerals. In the case of sandstone, the rock could be composed of feldspar, quartz, glauconite, and other minerals. Minerals in solutions can penetrate and stain the sandstone as well and affect the attempted streak test.
The streak color of sandstone is typically white or colorless, due to its composition of quartz grains. This can be tested by rubbing the sandstone on a streak plate to observe the color left behind.
Streak and Mohs hardness are descriptive and identifying terms for minerals. Because sandstone could be composed of a multitude of different rock particles or minerals, a specific hardness or streak cannot be attributed to them.
The streak test is not a very good identifier of rocks because rocks are composed of combinations of minerals which may have different color streaks. The streak test is mainly used in mineral identification. Even then, it is used in common with other indicators, like hardness, crystal system, and chemical composition.

To test out a streak, you can observe the behavior consistently for a period of time to see if it continues. For example, if you want to test if a winning streak in a game is genuine, keep track of the wins over multiple sessions. If the streak persists consistently, it is likely a true streak.
Sandstone is the rock that results when sand liquefies.
The streak should be olive greenish. My class did a streak test and found that out with pyrite. You want to do it? Get pyrite, a tile, and rub it across the tile. You should find out. But according to our results, pyrite had the olive green streak.
No, the hardness of a mineral does not affect its performance in the streak test. The streak test measures the color of the powdered form of a mineral when it is scratched against a streak plate, regardless of the mineral's hardness.

The streak of a mineral can distinguish between two samples that have the same color. The streak is often a different color. To test streak, use a streak plate. This is a piece of unglazed porcelain, like the back side of a tile.

Garnet leaves no color in a streak test .
