The hex color #1A0D88, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low contrast ratio when paired with similarly dark colors, potentially making text and interface elements difficult to read for users with visual impairments. To ensure accessibility, it is crucial to use #1A0D88 with light background colors or to use a lighter shade of the color as background, such as white or very light grays, to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. When used for interactive elements like buttons or links, sufficient visual cues beyond color alone should be provided, such as underlines or icons, to accommodate users with color vision deficiencies. Testing the color combination with accessibility evaluation tools is highly advisable.
