of coated abrasives having paper or cloth backing.” Saint-Gobain Corp. v. 3M Co., 90 USPQ2d 1425, 1447 (TTAB 2007). The Trademark Trial and Appeal Board, in In re Ferris Corp., 59 USPQ2d 1587 (TTAB 2000), held that the colour pink for wound dressings was functional and not registrable, as its colour resembles human skin and was selected for this specific purpose. In In re Orange Communications, Inc., 41 USPQ2d 1036 (TTAB 1996), the Trademark Trial and Appeal Board denied registration for the colours orange and yellow for public telephones and telephone booths, because it confers the goods better visibility under any lighting condition. Also, the colour coral was held functional for earplugs, because it makes them easier to see in safety checks. In re Howard S. Leight & Associates Inc., 39 USPQ2d 1058 (TTAB 1996). Aesthetical functionality bar In addition to the functionality bar, the colour cannot have an aesthetically functional purpose in order to be registrable or protected. In Brunswick Corp. v. British Seagull, for example, the United States Patents and Trademark Office's Trademark Trial and Appeal Board held that the black colour was not registrable for outboard motors: "[A]lthough the color black is not functional in the sense that it makes these engines work better, or that it makes them easier or less expensive to manufacture, black is more desirable from the perspective of prospective purchasers because it is color compatible with a wider variety of boat colors and because objects colored black appear smaller than they do when they are painted other lighter or brighter colors. The evidence shows that people who buy outboard motors for boats like the colors of the motors to be harmonious with the colors of their vessels, and that they also find it desirable under some circumstances to reduce the perception of the size of the motors in proportion to the boats." British Seagull Ltd. v. Brunswick Corp., 28 USPQ 2d 1197, 1199 (1993). Even though there is no direct function for the colour black in this case, protection was denied under the argument that consumers prefer it for aesthetic purposes. A similar judgement was entered in Deere & Co. v. Farmhand. Deere & Co. tried to establish exclusive use of its John Deere green colour as a trademark, in order to enjoin Farmhand from applying it to its products. Although the John Deere green colour does not provide any specific function
