The hex color #0A174D, also known as Gulf Blue, presents some accessibility challenges, particularly in text-based contexts. Its low lightness value (dark color) necessitates careful consideration of contrast ratios against background colors. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. When using #0A174D for text, it is recommended to pair it with a light background color to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Insufficient contrast can make text difficult or impossible to read for some users. Furthermore, avoid using #0A174D as the sole indicator for interactive elements; always provide additional cues such as labels, icons, or changes in state to ensure usability for all users.
