The color #1B547D, also known as Chathams Blue, presents some accessibility challenges.

According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, consider using #1B547D with lighter text colors such as white or very pale yellow, or pair it with darker background colors to increase contrast.
