The hex color #234C74, also known as Chathams Blue, presents several accessibility considerations for web developers. Its relatively dark hue means that it requires careful attention to contrast ratios, especially when used for text or interactive elements.

Lighter shades of yellow, white, or even carefully chosen lighter blues can provide adequate contrast. Furthermore, consider users with visual impairments, such as color blindness. Avoid relying solely on color to convey important information; supplement color cues with text labels, icons, or patterns to ensure that all users can understand and interact with the content effectively. Tools like online contrast checkers can be invaluable in verifying compliance with accessibility standards.
