Its relatively low saturation and dark value make it a sophisticated choice for backgrounds and accents, although careful consideration should be given to contrast when pairing it with text or other design elements to ensure accessibility and readability.

The hex color #1E4A7F, also known as Chathams Blue, presents specific accessibility challenges, especially when used as a background or text color. Its relatively low luminance value of 0.075 means that it requires very light text to meet WCAG (Web Content Accessibility Guidelines) standards for contrast. A contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text. Therefore, when using #1E4A7F, ensure that the foreground text is white or a very light shade of gray to provide sufficient contrast for users with visual impairments. Tools like contrast checkers can help verify compliance. Additionally, avoid using this color for elements that convey important information solely through color, as colorblind users might miss the distinction. Supplement with text labels or other visual cues to ensure inclusivity.
