The hex color #1B4C80, also known as Chathams Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it's crucial to ensure that the foreground text color provides sufficient contrast to meet WCAG guidelines. A light text color, such as white (#FFFFFF) or a very light shade of gray, would be necessary to achieve acceptable contrast ratios for readability. For individuals with low vision or color blindness, inadequate contrast can make content difficult or impossible to perceive. Tools like contrast checkers can help evaluate the contrast ratio between text and background colors, ensuring compliance with accessibility standards. Furthermore, avoid relying solely on color to convey important information; always provide alternative textual cues or visual indicators.
