The hex color #154B86, also known as Chathams Blue, presents some accessibility challenges, particularly when used for text. Its relatively low lightness value of 0.17 means that it requires careful pairing with contrasting colors to ensure readability. When using this color for text, a light background is essential to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools such as contrast checkers can help web developers verify the contrast ratio between the text and background colors. Using #154B86 as a background color is more forgiving, but the text placed on top should still be of a light hue, such as white or a pale yellow, to guarantee sufficient contrast. Additionally, consider providing alternative visual cues, like icons or underlines, to enhance accessibility for users with visual impairments.
