The color #1B1187, also known as Deep Koamaru, presents accessibility challenges due to its dark hue. When used as a background, it necessitates very light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1 respectively. It is crucial to test color combinations using accessibility tools to guarantee that they meet these standards, particularly for users with visual impairments. Using this color for small text or intricate details against a dark background is strongly discouraged. Careful consideration of text size, font weight, and spacing can help improve readability, but alternative, lighter colors may be more suitable in many cases to optimize accessibility.
