Binding text read: IFAB Law 4.3 requires kits that distinguish the teams and officials, without mentioning colour vision. UEFA describes its CVD practice (EURO 2020 kit selections made with teams, e.g. a black away kit for Croatia) as best effort in a news article; the Equipment Regulations article that would carry any rule was not readable. World Rugby's July 2024 document is the one text read that states a policy: for its tournaments from 1 January 2025 a dark primary kit needs a light alternate (and vice versa), with World Rugby directing the kit when a clash is found. Shared checks: greyscale look-alike test, one dark and one light kit, avoid single-colour mid red/orange/green kits, whole-shirt patterns, sock/pitch contrast, number contrast, and approval on physical samples rather than CAD simulations. TV viewing (wide-angle shots, small screens) is named as an aggravating condition, but no inspected text addresses scorebug team-colour chips.
