Colouring Pigments or Stainers: As the name implies, it is a colouring pigment which is added to the paint, when the colour desired for a paint is different from the base of a paint. Generally for white, black and very dark colour shades, the base itself is chosen of the same colour. In case of light paint shades, the colouring pigment is added to the white paint.
