The color #1E4F7D, also known as Chathams Blue, presents some accessibility challenges. With a relatively low luminance, it may not provide sufficient contrast when used as text against a white or light-colored background. This can make it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast is crucial for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text.

Evaluating the contrast ratio using online tools is advisable to ensure compliance with accessibility standards. Furthermore, avoid using this color as the sole means to convey important information; supplement it with text or icons for users who may have difficulty perceiving it.
