The hex color #145287, also known as Chathams Blue, presents some accessibility considerations for web developers. Due to its relatively dark hue, it's crucial to ensure sufficient contrast when used as a background or text color. 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 its background. Using a color contrast checker is advisable to verify compliance. When used for text, lighter colors like white, light yellow, or pale green could provide adequate contrast and readability. Conversely, as a background color, pairing it with white or very light text can improve visibility. Developers should also consider users with visual impairments who may rely on screen readers. Semantic HTML and ARIA attributes can further enhance the accessibility of content using this color.
