Accessibility Requirements
Some people with visual impairments interpret color and contrast differently, making it difficult to access information communicated only by color. Making colors accessible usually means creating color combinations that provide enough contrast that the content is clearly distinguishable from the surrounding page.
Based on Web Content Accessibility Guidelines (WCAG), we require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large or bolded text.
