The color #1A497D, also known as Chathams Blue, presents some accessibility challenges. Its relatively dark hue means it requires careful consideration when used as a foreground color against a background. According to WCAG guidelines, sufficient contrast is crucial for readability. A small text using #1A497D on a white background would likely fail contrast checks, making it difficult for users with visual impairments to read. To improve accessibility, consider pairing it with lighter colors like whites, creams, or very light yellows to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using it for crucial interactive elements without proper visual cues, as users might struggle to identify them. Providing alternative text descriptions for images using this color is also recommended.
