The color #1811C5, a dark blue, presents significant accessibility challenges, particularly in text and user interface design. Its low lightness value (being a dark color) results in poor contrast against commonly used background colors like white or light grays. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is crucial for users with visual impairments to perceive content effectively. To ensure accessibility, it is essential to use #1811C5 with light backgrounds or paired with very light foreground colors. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Tools like contrast checkers can help evaluate and adjust color combinations. Moreover, avoid using this color as the sole indicator for interactive elements; supplement it with text labels or icons. When using this color for information delivery, ensure that the information is also conveyed through other means, such as text or symbols, to accommodate users with color blindness.
