The hex color #1109dd, a dark blue, presents several accessibility considerations for web developers. Due to its low lightness value, it offers poor contrast when used as text against a white background. This can make it difficult for users with visual impairments, including those with low vision or color blindness, to read the text. According to WCAG guidelines, sufficient contrast is essential for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a lighter color for text on a #1109dd background, or vice versa, will significantly improve accessibility. Tools are available to check the contrast ratio between foreground and background colors to ensure compliance with accessibility standards. Ensure all interactive elements using this color have clearly defined focus states to aid keyboard navigation.
