Colour pigments are the specific additives used to impart a desired color to polymers. These pigments are finely ground materials that can be dispersed throughout the polymer matrix. They are designed to provide a wide range of hues and shades, helping manufacturers achieve exact color specifications for their products.

Unlike other additives, such as fillers, which are primarily used to enhance strength or reduce material costs without significantly affecting color, or stabilizers, which provide resistance against degradation from environmental factors, colour pigments play a crucial role in aesthetic appeal. Plasticisers, on the other hand, are added to increase the flexibility and workability of polymers, but do not contribute to the coloration of the material.

Overall, colour pigments are essential for ensuring that polymers meet visual design requirements in various applications, making them the correct choice for this question.
