At the bottom of a confirmation mail from UPS, I saw this:

Quote

Copyright (c) 2008 United Parcel Service of America, Inc. UPS, het UPS
beeldmerk en de kleur bruin zijn merken van United Parcel Service of America.

Literally translated it says: the UPS logo and the color brown are trademarks of United Parcel Service of America.

Does this mean we can't use the color brown anymore without infringing this trademark?
