T-Mobile utilizes magenta heavily in its branding and in fact owns registration 3,263,625 on the supplemental register, consisting of a magenta square, described as: The color(s) magenta is/are claimed as a feature of the mark. The mark consists of the color magenta alone, which is the approximate equivalent of Pantone Matching System, Rhodamine Red U, used on the background of product displays and advertisements found in a store. AT&T subsidiary AIO, has now adopted a logo that looks sort of magenta-ish, and is allegedly using magenta in store displays and the like. On my computer screen, AIO’s logo looks sort more like Pantone’s magenta haze (pantone 1825) , than rhoadamine red.
