The {{Infobox rainbow season}} template is used to define an infobox for a Rainbow Cup season.
Here is how you use it:
{{Infobox rainbow season
| season = 1
| start_date = 2021-05-24
| end_date = 2021-05-26
| champion_abbr = SFBS
| unwest_league_seed1_abbr = LBFB
| unwest_league_seed2_abbr = TB
| unwest_league_seed3_abbr = SS
| unwest_league_seed4_abbr = OSHA
| west_league_seed1_abbr = DET
| west_league_seed2_abbr = SFBS
| west_league_seed3_abbr = SAC
| west_league_seed4_abbr = MILF
}}
The {{Infobox season}} template will pass these arguments to the {{Infobox}} template, inserting the right bits of information in the right places to produce this:
