The color #1B477C, also known as Chathams Blue, presents moderate accessibility challenges. Its relatively dark hue means it generally works well with lighter text, enhancing readability. However, when paired with other dark colors, contrast can become an issue, making content difficult to read for users with visual impairments.

Consider using color contrast tools to verify compliance and adjust text or background colors as needed. Additionally, avoid relying solely on color to convey important information, as this can exclude users who are colorblind. Supplement color cues with text labels, icons, or other visual indicators to ensure inclusivity.
