Limestone is usually white, but may be colored by impurities, iron oxide, making it brown, yellow, or red and carbon making it blue, black, and gray.
Limestone is a sandy color but may be blackish or greyish
Sandstones and limestones vary greatly in color and can be white, tan, purple, brown, red, black, green, and gray.
White(ish), tan, brown, gray, and black are all colors found in limestones.
it is white

Limestone can be pretty dull at times.
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
Marble is the metamorphosed result of limestone. Therefore, marble is metamorphic.

limestone pavement is formed by leaving exposed limestone for ages
Travertine is a fancy name for limestone with color.
The Great Pyramid was the color of Oolitic limestone- a kind of honey color. When it was built, the outside was covered in a layer of polished white fine grained limestone, but had been removed later to build Cairo

Redwall limestone is named after the Redwall Limestone cliffs in the Grand Canyon, which are composed of this type of rock. The color of the limestone can vary depending on its mineral content and environmental conditions.
Fossils are actually what gives Irish limestone its blue color. It is a very compact rock type. Many contain oyster fossils and other organic materials that compress to make the color.

There are different types of limestone rock in the UK which differ in colour. Carboniferous limestone is greyish and hard and made from the remains of corals. Jurassic limestone is yellowish and softer. It is oolitic (made from little eggs of calcite). Cretaceous limestone is very white and chalky. It is made from the skeletal remains of planktonic organisms.
Limestone with a pure white color normally formed in clear, warm water. It could also have formed in a river estuary as well as river beds.
The principal component of limestone is the mineral calcite, but limestone frequently also contains the minerals dolomite (CaMg(CO3)2) and aragonite (CaCO3). Pure calcite, dolomite, and aragonite are clear or white. However, with impurities, they can take on a variety of colors. Consequently, limestone is commonly light colored; usually it is tan or gray. However, limestone has been found in almost every color. The color of limestone is due to impurities such as sand, clay, iron oxides and hydroxides, and organic materials. All limestone forms from the precipitation of calcium carbonate from water. Calcium carbonate leaves solutions in many ways and each way produces a different kind of limestone. All the different ways can be classified into two major groups: either with or without the aid of a living organism.
