The color #1C4C7C, also known as Chathams Blue, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) AA standard for contrast ratio, which requires a minimum ratio of 4.5:1 for normal text. This can make it difficult for users with visual impairments to read the text comfortably. Therefore, it's essential to use this color carefully in combination with other colors. To improve accessibility, consider pairing it with lighter shades of yellow, beige, or even light gray to ensure sufficient contrast. Another option is to use it for larger text elements or graphical elements where contrast requirements are less strict. Tools like contrast checkers can help to verify compliance with accessibility standards.
