The color #18149A, also known as Ultramarine, presents accessibility challenges due to its dark nature. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Failure to meet these ratios can make the content difficult to read, especially for users with visual impairments. When used for text, #18149A should be paired with a significantly lighter background. Consider using accessibility evaluation tools to verify contrast ratios and ensure compliance with accessibility guidelines. Also, avoid using this color as the sole means of conveying information, as colorblind users may not be able to distinguish it effectively. Supplement color cues with text labels or other visual indicators.
