The color #2100B4, a deep shade of blue, presents some accessibility challenges, especially when used as a text color. Its relatively low luminance (brightness) can make it difficult to read against backgrounds that are not sufficiently light. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast between text and background is crucial for readability. For normal-sized text, a contrast ratio of at least 4.5:1 is recommended, while for large text, a ratio of 3:1 is acceptable. When using #2100B4 for text, it's important to pair it with a very light background color to meet these contrast requirements. White (#FFFFFF) or very light grays would be suitable choices. If using it for interactive elements like buttons or links, consider providing alternative visual cues, such as underlines or borders, to ensure that users can easily identify them, especially for users with low vision or color blindness. Furthermore, avoid using this color as the sole indicator of important information or actions, as users with color vision deficiencies may not be able to distinguish it effectively. Always test color combinations using accessibility evaluation tools to ensure compliance with WCAG standards.
