The hex color #1805b1 presents a significant challenge for accessibility due to its very dark hue. When used as a foreground color for text, it necessitates a very light background to provide sufficient contrast for readability, adhering to WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Otherwise, users with visual impairments, including those with low vision or color blindness, may struggle to distinguish the text from the background. Similarly, when used for interactive elements like buttons or links, ensuring adequate contrast is crucial for users to identify these elements and interact with them effectively. Using online contrast checkers is advisable to verify compliance.
