Designing accessible color systems

  • TLDR: engineers at Stripe examine the WCAG 2.0 minimum contrast ratio for text and how they arrived at their new accessible colour palette. It goes into great detail on how colour is represented on computer screens and how humans perceive colour, before describing the tool they’ve built to visualise perceptual contrast to help them to arrive at the right choice. Unfortunately there’s no link to the tool itself, nor to its code.
