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.

Is marble made from igneous rock?
Marble is not made from igneous rock. Marble is a metamorphic rock made from either limestone or dolormite. Its texture is non-foliated. Non-foliated metamorphic rocks are those which either receive equal pressure from all sides as they form, or they are those which were formed from minerals that did not have any distinct patterns of growth. Pure marble is white. The swirling and splotches of color in marble come from substances such as clay, sand, and silt in the limestone. So as the limestone is changing into marble, the clay, sand, silt and other elements in the limestone become swirls or splotches of color.
