Template:NFLPrimaryColor/doc

Usage
This template can be used to automatically fill the primary color used by each respective team in the National Football League. It can be used in conjunction with NFLSecondaryColor and other NFL color templates. It takes only one required parameter, which is the team name and one optional parameter, which is the year. If the year is provided it will be used to select the color scheme used at that point in time in the case of franchises whose color schemes have changed over time. If the year is not provided, the current color scheme will be used.

Deprecated method to get non-current color
Prior to the implementation of the year parameter, the method to designate non-current color schemes was to specify an alternate team name. For example,   would yield the primary color in use by the Broncos from 1997 through 2011. A simpler way to achieve this same result using the year parameter would be  . This requires no special knowledge of the correct "code" for the previously used color scheme.

While the old code word based methodology has been retained in the interest of backward compatibility, the new method using the year parameter should be used going forward.
