Limestone can and does appear in shades of green, due to impurities.
Limestone can come in grey, yellow, white and a bunch of other colors too.
White limestone is formed from the accumulation of calcium carbonate from the remains of marine organisms like coral and shells. This accumulation often occurs in shallow seas and is deposited from the water onto the sea floor over time, eventually forming limestone rock.
because they were to HEAVY
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 has a white streak.
Pure white limestone often forms in areas where the limestone has experienced very little exposure to impurities or contaminants during its formation process. This can happen in environments such as deep ocean basins, where the limestone can accumulate without being mixed with other sediments or minerals.
A streak is the color of the powdered mineral left behind when the mineral is rubbed against a hard, rough surface. Limestone typically has a white streak due to its composition of calcium carbonate.
No, limestone is not volcanic. It is a sedimentary rock that is formed from the accumulation of minerals like calcite and aragonite, which come from organic remains in bodies of water. Limestone is not formed through volcanic processes like igneous rocks are.
The main types of limestone are chalk, coral limestone, travertine, and tufa. Chalk is soft and white, coral limestone contains coral and other marine organisms, travertine is formed by hot springs, and tufa is a porous rock formed by calcium-rich water.
