The hex color #1937B1, or Persian Blue, presents moderate accessibility challenges. Its contrast ratio against white (#FFFFFF) is approximately 4.6:1, which meets the WCAG AA standard for normal text but falls short of the AAA standard. When used for larger text (18pt or 14pt bold), it meets the AA standard. Against black (#000000), the contrast ratio is approximately 4.5:1, also meeting AA for normal text. To improve accessibility, consider using a lighter shade of text on this background or a darker shade of blue. Ensure that interactive elements, such as buttons and links, have sufficient contrast to be easily identifiable. Provide alternative text for images and other non-text content to ensure usability for users with visual impairments. Proper semantic HTML structure and ARIA attributes can further enhance accessibility.
