Synthesis only. Seven checks can be traced to the inspected texts: (1) list every element where colour carries meaning (BBC mobile audit step); (2) add a non-colour cue such as label, logo, tick/cross (BBC Trust remedies; fans' proposal); (3) run the palette through a CVD simulator (named by the Trust as used in 2015; model unspecified); (4) test text/background contrast (WCAG AA on web and app; TV only "good contrast"); (5) greyscale or monochrome screen (BBC broadcast guidance; UEFA, World Rugby for kits); (6) check the rendered output on real or virtual lighting and small screens (Trust; World Rugby); (7) do not rely on narration. No inspected source gives a numeric pass/fail threshold for TV graphics, a validated order of the checks, or a test of any scorebug, so this list is a proposal with an experiment sketched for later.
