Sandstone is composed of many individual grains of sand. Thus its colour will depend entirely on the colours of the source of sand. (And of any subsequent staining.) It could be quite uniform, or it could be mottled.
A fine sandstone has had its source sands pre-selected by some process, and these are likely to have had colour sorting done as well quite by accident.
For example, slates are usually quite uniform in colour, largely determined by the deposition process, and the colour of the source system. [Slates would not be considered sandstones because the particles are too fine, but the principle applies.]
Arkansas Stone is a very fine grained natural sandstone used as an abrasive.
What else can I help you with?
Do conglomerate rocks have a mottled appearance?
Yes, they contain pebbles of other rock varieties in a finer matrix, this gives them a mottled look.
What is responsible for the mottled appearance of the Sun's surface known as granulation?
Granulation on the Sun's surface is caused by convection currents of hot plasma rising and cool plasma sinking beneath the surface. As hot plasma rises, it cools and begins to sink back down, forming the characteristic mottled appearance.

Does sandstone have crystals?
Sandstone typically does not have crystals. It is primarily composed of sand-sized mineral particles that are cemented together, giving it a granular appearance. If sandstone does contain crystals, they are usually very small and not easily visible to the naked eye.
Are all sandstone the same size?
No, sandstone can vary in size depending on the specific composition of minerals and grain size. Sandstones can have a range of grain sizes from very fine to coarse. The size of the sand grains in the sandstone will impact its appearance and texture.

The appearance of sandstone when it contains iron compounds?
Sandstone containing iron compounds can exhibit a range of colors, including shades of red, brown, and yellow, depending on the concentration and oxidation state of the iron. The iron compounds, such as hematite or goethite, give the sandstone a characteristic rusty appearance. Over time, these iron compounds can also contribute to the weathering and erosion of the sandstone.
When was Mottled Petrel created?
Mottled Petrel was created in 1844.
