Team colors, with the contrast maths already done
Hexadecimal, red green blue, hue saturation lightness and cyan magenta yellow black values for 41 teams across four leagues — 68 distinct colours, every figure computed from the values rather than typed by hand.

What this does that other colour sites do not
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.

Why the last row matters
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.
