The hex color #1A4D8F, also known as Chathams Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of 0.053 makes it a dark color. When used as a background, sufficient contrast is essential. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet Level AA compliance. Pairing #1A4D8F with light colors such as #FFFFFF (white), #FAF9F6 (seashell), or #E0FFFF (light cyan) can achieve acceptable contrast ratios. Tools like WebAIM's Contrast Checker can help verify contrast ratios. Avoid using this color for essential interactive elements or small text without careful consideration of its contrast against the background. Providing alternative styling options, such as high contrast modes, can further improve accessibility for a wider range of users.
