Feb 1, 2026

February 2026: Delivered a unified color system and improved template guidance across the GOV.UK Frontend and Design System, with a focus on business value, accessibility, and maintainability. Highlights include standardizing link color to the 10% blue across components (footer, navigation, cookie banner), deprecating the surface-link color, and updating related Sass configurations and tests. Documentation and guidance for functional colours were expanded with usage examples and clearer deprecation messaging. Page Template guidance was tightened to align blocks (govukHeader, govukFooter, govukServiceNavigation) and remove unused examples. Per-service cookie banner guidance was clarified. In parallel, several maintenance fixes reduced test fragility and cleaned up deprecated options.
