The hex color #1C487F, also known as Chathams Blue, presents some accessibility challenges, primarily due to its relatively low luminance. When used as a background color, it requires careful selection of foreground text colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Therefore, pairing #1C487F with light text colors like white (#FFFFFF) or very light grays is essential. Using darker text colors against this background can make the text difficult to read, especially for individuals with visual impairments. Designers should use contrast checking tools to verify that their color combinations meet accessibility standards. Additionally, providing alternative styling options, such as allowing users to adjust the color scheme, can further enhance accessibility.
