The Deutsche Telekom - and its subsidiary T-Mobile - antagonize designers and creatives by claiming a trademark for the color magenta at the European brandoffice. No other company should be allowed to use this color for their stationary advertising campaigns. Strictly speaking, this would lead to the fact that only the Deutsche Telekom would be allowed to print in full color: Finally nearly all full color prints are realized with the four colors C - cyan, M - magenta, Y - yellow and K - black.
Graphic designers in the Netherlands started a "consumer created content campaign" against the prohibition to use magenta in advertisement.

As a result, the claiming of the color magenta as a trademark may damage the value of the Deutsche Telekom image substantially.
