Continuing my re-generation of the pro team colors images (complete with Hex and RGB values), are the following football leagues:
- National Football League Europa (2007)
- National Football League Europe (1998 through 2006)
- United States Football League (1983 through 1985)
- World Football League (1974 through 1975)
- World League of American Football (1991 through 1992; 1995 through 1997)
- XFL (2001)
I will continue to bang out some of these smaller sets of team colors before moving on to tackle the bigger leagues (MLB, NFL, NBA, NHL).
