The color #180698, a deep ultramarine, presents considerable accessibility challenges. Its dark hue results in low contrast against light backgrounds, making text or interactive elements difficult to perceive for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. To enhance accessibility, consider pairing #180698 with very light colors like #FFFFFF or #F0F0F0 to achieve the required contrast. Avoid using it for crucial information or interactive elements without careful attention to contrast. Also, providing alternative text descriptions for images and icons is essential for screen reader users to understand the context.
