The NHL (and formerly the NBA) enforces the color/white rule strictly; any NHL team seeking to wear white at home must get express permission from the league office to do so. In minor league hockey, the rules are set in both the AHL and ECHL where the team wears white jerseys at home during one half of the season, then wears the color jerseys during the other half at home, and vice versa on the road.[4] In the NFL, the rules state that the home team has the first choice of color, with the visiting team forced to choose a contrasting color; an exception was Color Rush, in which uniform choices were coordinated by the league itself.[5]
