The color #1A477E, also known as Chathams Blue, presents some accessibility considerations for web development. Its relatively dark hue implies that it will generally need to be paired with lighter text or 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. Using a color contrast checker is crucial to verify that the combination of #1A477E with foreground colors meets these standards. Failure to meet these standards can make content difficult to read for users with visual impairments. Moreover, consider providing alternative styling options for users who may need to customize the color scheme to suit their individual needs. Ensure that links and interactive elements using this color are clearly distinguishable from surrounding text through sufficient contrast and additional cues like underlines or icons.
