Accessible High Contrast UI Colour Palette

About this palette

Accessible High Contrast UI is a curated five-colour palette designed for public services, forms, accessibility-first products and high-clarity interfaces. Black and white establish maximum clarity while blue and amber provide strong action and attention cues.

The colours are #000000, #FFFFFF, #005FCC, #FFBF47, #E5E7EB. Use the darkest and lightest values to establish hierarchy first, then introduce the supporting colours for accents, surfaces and visual rhythm.
