Several sites list team colour codes. This one competes on the things none of them provide: contrast computed per pairing rather than omitted, a clash verdict for any two teams, a stated source and check date on every value, and a preflight tool that tells you whether a design will survive printing.

Team logos and helmet marks are registered trademarks. Sites that host them — often under an “educational use” line — are distributing other parties' marks on a commercial page. Rendering every swatch from numeric values avoids the question entirely: colour values are factual data and free to cite.
