This makes content difficult to read for users with visual impairments, including those with low vision or color blindness. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability. A contrast ratio of at least 4.5:1 is recommended for normal text, and 3:1 for large text. To improve accessibility, consider using #1A0133 sparingly, primarily for decorative elements. When using it for text or interactive elements, always pair it with a very light color, such as white (#FFFFFF) or a light shade of gray, to meet the contrast requirements. Tools are available to test color contrast ratios to ensure compliance with accessibility standards. Avoiding #1A0133 altogether for critical information is another valid approach to ensure optimal user experience for everyone.
