The color #170DA7, a deep ultramarine, presents several accessibility considerations for web developers. Its dark hue provides inherent contrast against lighter backgrounds, which is crucial for readability, especially for users with visual impairments. However, when pairing it with other dark colors, the contrast ratio can drop below the WCAG (Web Content Accessibility Guidelines) recommended levels. To ensure accessibility, developers should verify a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14 points bold or 18 points regular) against the background color. Using tools like contrast checkers can aid in this process. Furthermore, avoid using this color as the sole indicator of interactive elements; supplement it with text labels or icons to accommodate users with color vision deficiencies. It is important to test with various color blindness simulators to ensure the design remains understandable and usable for all users.
