A trademark does not have to be a word, logo or symbol.

This article illustrates some of the more unique trademarks in the marketplace. People generally think of a trademark as a word, phrase, logo or symbol, but it can basically be anything that identifies a particular good or service. For instance, UPS has a trademark on the color brown for delivery services, and Tiffany has a trademark on the robin's egg blue color in connection with jewelry and handbags.
