The hex color #1B467C, also known as Chathams Blue, presents specific accessibility considerations, particularly for web development. Its relatively low luminance value (approximately 0.05) means that it requires careful pairing with text and other interface elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. When using #1B467C as a background, it is crucial to use light-colored text (e.g., white or light yellow) to meet these contrast requirements. Failure to provide adequate contrast can make content difficult or impossible for users with visual impairments to read. Tools like contrast checkers can assist developers in verifying compliance. Also, avoid using this color alone to convey important information, supplement it with text or icons.
