Tricking is a method for indicating the tinctures (colours) used in a coat of arms by means of text abbreviations written directly on the illustration. Tricking and hatching are the two primary methods employed in the system of heraldry to show colour in black and white illustrations.

Hatching is a conventional system for monochrome denotation of heraldic armory, whereby the tinctures (colours) are represented by dots and lines. This technique is employed in cases where colours, for either aesthetic, practical or economic reasons are not reproduced – e.g. on surfaces such as woodcuts or engravings, seals and coins.
