The color #1E4C7A, also known as Chathams Blue, presents some accessibility considerations for web design. When used as a background color, it's crucial to ensure sufficient contrast with text and other foreground elements. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. Using a light color like #FFFFFF (white) or a bright yellow as the text color will improve readability. It's advisable to test color combinations using online contrast checkers to confirm compliance. Over-reliance on color alone to convey information should be avoided, and alternative cues such as text labels or icons should be provided for users with visual impairments.
