The color #0A3B66, also known as Astronaut Blue, presents some accessibility challenges, primarily due to its dark hue. When used as a background color, it necessitates light-colored text to ensure sufficient contrast for readability. 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 compliance. Given its darkness, #0A3B66 might require very light shades of white or yellow to achieve this contrast. Careful consideration should be given to users with visual impairments who may struggle to differentiate between similar dark shades. Using color contrast checking tools is crucial to verify that the chosen text color meets accessibility standards. Furthermore, avoid using color alone to convey important information; always provide text labels or other visual cues to ensure inclusivity for all users.
