The hex color #1A0B8D, also known as Ultramarine, presents some accessibility challenges, especially when used as a background color for text. Due to its dark nature, it requires very light text to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA standards. Using a color contrast checker is essential to verify that the chosen text color provides adequate readability. Avoid pairing #1A0B8D with mid-tone or dark colors, as this will likely result in poor legibility for users, including those with visual impairments. When using this color for interactive elements, ensure that hover and focus states also maintain sufficient contrast to provide clear visual cues for users.
