The color #1721CF, Persian Blue, presents significant accessibility challenges, particularly regarding color contrast. When used as text against a white background, it fails to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (AA) and large text (AAA). This means that users with visual impairments may find it difficult or impossible to read. To improve accessibility, consider pairing this color with a much lighter background, such as a pale yellow or off-white, or using it sparingly for decorative elements rather than crucial textual content. For text, a lighter tint of blue or a contrasting color like yellow or white would be preferable to ensure readability for all users, including those with low vision or color blindness. It's important to always check contrast ratios using accessibility tools to ensure compliance with accessibility standards.
