The hex color #1D0299, a deep ultramarine, presents significant accessibility challenges, especially when used as a background color for text. Due to its low luminance, achieving sufficient contrast with lighter text colors is crucial. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards. Using a very light color such as white or a pale yellow for text is necessary to ensure readability for users with visual impairments. Careful consideration should be given to font sizes and weights, as thinner fonts may further reduce readability. When using #1D0299 for interactive elements, providing clear visual cues for hover and focus states is also important to improve usability for all users. Ensuring that interactive elements have distinct boundaries is also essential. Testing the color combination with accessibility evaluation tools and users with disabilities is highly recommended.
