A method of colouring cementitious building materials such as concrete is disclosed. The method uses flowable, spray-dried, particulate formulations of inorganic pigments prepared using a selection of formulants that do not substantially effect primary ettringite formation. Quantities of the formulations may conveniently be dispensed into a slurry of cement and water by gravimetric or volumetric means.
