The color #050494, a deep ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance makes it difficult to read against many backgrounds, especially lighter ones. According to WCAG guidelines, using this color for text requires a very high contrast ratio to be considered accessible. A contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text. Therefore, when using #050494, careful consideration must be given to the foreground color choice. Light yellows, oranges, or near-white shades are often necessary to achieve sufficient contrast. Furthermore, avoid using this color for crucial interactive elements without providing clear visual cues and redundant accessibility features such as ARIA attributes to ensure usability for users with visual impairments or color vision deficiencies. Testing with accessibility evaluation tools is highly recommended.
