The color #17179D, also known as Ultramarine, presents some accessibility challenges, particularly in text-based applications. Due to its dark hue, sufficient contrast is crucial when pairing it with text. White or very light shades of yellow or other bright colors are typically needed to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Using a contrast ratio checker is highly recommended to ensure compliance, especially for users with visual impairments. When utilizing this color as a background, be mindful of the foreground elements; ensure they stand out clearly. Avoid using #17179D for crucial UI elements such as buttons or links without proper contrast. Non-text elements such as icons also need to meet contrast requirements. Larger text sizes can help improve readability at lower contrast ratios, but it's crucial to test these combinations with real users to gather feedback and refine the design.
