What do BBC's own colour rules for graphics say, and how do the broadcast, online and app rules differ in what they require and how they are tested?

Three BBC rule sets appear in the inspected texts. The broadcast editorial guidance (read only as quoted in the 2016 Trust decision) says to use colours with good foreground/background contrast, names green, yellow or white as best foreground colours, says to avoid pure blues, reds and mauves, and offers a monochrome spot-check; it sets no CVD-specific test or numbers. The online Future Media rules (also read only as quoted in the decision) are MUST statements: information carried by colour must also be available without colour, WCAG 2.0 AA contrast via Snook, and no colour pairs indistinguishable to colour-blind people (check with Vischeck). The current BBC Mobile Accessibility Guidelines (read directly, observed 22 Oct 2026) say colour must not be the only carrier of meaning, require WCAG 2.1 AA contrast, and give a test procedure. The Trust found the broadcast and online sets significantly different.
