The color #1809AB, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in a low contrast ratio against lighter backgrounds commonly used in web design. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. Text or interactive elements using #1809AB on a white or light-colored background may fail to meet minimum contrast requirements, making it difficult for users with low vision to perceive the content. To improve accessibility, consider using lighter shades of blue or pairing #1809AB with much lighter foreground colors to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using this color as the sole indicator for interactive elements, as colorblind users may not be able to distinguish them.
