The color #154B83, also known as Chathams Blue, presents some accessibility challenges. Its relatively low luminance value of 0.047 means that it requires careful consideration of contrast when used with text or other interface elements. 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 (14pt bold or 18pt regular). When using #154B83 as a background, ensure that the foreground text is a light color like white or a very pale yellow to meet accessibility standards. Tools like contrast checkers can help verify compliance. Additionally, avoid using this color as the sole indicator for interactive elements like links or buttons, as users with visual impairments may not be able to distinguish them. Providing supplementary cues, such as underlines or icons, enhances usability for everyone.
