The color #1C4A7C, also known as Chathams Blue, presents specific accessibility considerations. Its relatively dark hue necessitates careful selection of foreground colors to ensure sufficient contrast, especially for text. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against backgrounds. When using #1C4A7C, lighter shades of yellow, white, or light gray are advisable for text to meet these standards. Insufficient contrast can significantly hinder readability for individuals with visual impairments, including those with low vision or color blindness. Designers should leverage contrast checking tools during the design process to validate compliance with accessibility benchmarks and refine color pairings accordingly. Furthermore, avoid relying solely on color to convey essential information; employ supplementary cues like text labels or icons to ensure inclusivity. Regular accessibility audits and user testing with diverse audiences are also crucial to identify and address any unforeseen usability challenges associated with this color choice.
