Pure quartz is a colorless mineral, and so a pure quartz sandstone will appear white due to multiple reflections and refractions between grains. However, impurities in the sandstone may give it some other color. What color it turns out as depends on the impurities. For example, iron oxide will produce a red sandstone.
Sandstone is primarily composed of quartz, feldspar, and clay minerals. Other common minerals present in sandstone include mica, calcite, and iron oxides. These minerals give sandstone its characteristic texture and color.
The principal mineral in sandstone is quartz. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles, with quartz being the most abundant mineral present.

The metamorphic rock that often forms from sandstone adjacent to magma near Earth's surface is called quartzite. When sandstone is subjected to high temperatures and pressures due to nearby magma, the quartz grains in the sandstone recrystallize, resulting in a dense, hard rock. Quartzite is typically characterized by its interlocking quartz crystals and can vary in color depending on the mineral content of the original sandstone.
Quartz sandstone, aka arenite, can form the metamorphic rock called quartzite.
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.
Impurities gives quartz its many beautiful colors.
Arkose is a type of sandstone that contains more than 25% feldspar, along with quartz and other minerals like mica, magnetite, and hematite. The feldspar content gives arkose its distinct pinkish color.
environments not conducive to optimum coral growth, is conducive to quartz sandstone.

Generally, arkosic sandstone would travel less distance before deposition compared to quartz sandstone. This is because arkosic sandstone is typically less resistant to weathering and erosion due to its higher content of feldspar, which weathers more easily compared to quartz. Quartz sandstone, being more durable, can travel further before getting deposited.

how about u give me the answer
Maybe lechatelierite? Or crystal (as in quartz glass)?
Sandstone is usually composed of grains of quartz with a calcitic or silica based cement.
