The color #0643A0, a deep cobalt blue, presents several accessibility considerations for web developers. Its low luminance value of approximately 4% means it requires careful pairing with contrasting colors to ensure readability. When used as text, it should be placed against a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio, specifically aiming for a ratio of at least 4.5:1 for normal text and 3:1 for large text. For graphical elements and UI components, a contrast ratio of 3:1 is necessary. Avoid using this color for crucial interface elements without sufficient contrast, as it can be difficult for users with visual impairments, including those with low vision or color blindness, to perceive them clearly. Ensuring sufficient contrast will significantly improve the user experience for all visitors.
