The color #18487F, also known as Chathams Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low lightness value means that it may not provide sufficient contrast when used as text against a dark background, or as a background color for dark text. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #18487F, it is imperative to pair it with a very light color to ensure adequate contrast. Tools are available online to check the contrast ratio between two colors, and they should be used during the design process. When this color is used on interactive elements, ensure that the contrast is sufficient also for the hover and focus states of buttons and links. Careful consideration of color combinations will help make your website or application more accessible and user-friendly.
