More terms and abbreviations are defined on Brush Creek Trading Company's glossary of patch terms .
Color is subjective and often difficult to characterize.
There are scientific color numbering systems in use in the publishing and textiles industries, but collectors tend to use more descriptive terms. The following colors and their corresponding abbreviations were used in describing color for this catalog. I have started adding links to images showing examples of these colors. In order to keep things as simple as possible the border of the patch will be the color in question. Please remember, the particular shade in each example is not necessarily the only shade to be called that color.
