The Fed is always purple and the Ex is in a different color for each division and grey for the overall corporation use. The original "FedEx" logo had the Ex in orange; it is now used as the FedEx Express wordmark. The FedEx wordmark is notable for containing a hidden right-pointing arrow in the negative space between the "E" and the "X", which was achieved by designing a proprietary font, based on Univers and Futura, to emphasize the arrow shape.
