The colour of the abrasive side of the products has no significance with regard to their quality, but is often useful for identifying the products, based on tradition and local marketing practice.

The use of raw materials may also limit the use of individual colouring. Say, the use of silicone carbide grains is often identified by a black sanding surface as this raw material is black by nature and therefore difficult to colour.
