The color #185A6A, also known as Chathams Blue, presents some accessibility challenges, especially when used as a background or text color. Its relatively low lightness value (around 30%) means that it requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. Using #185A6A for text on a white background may not meet these contrast requirements, potentially making it difficult for users with visual impairments to read the content. Therefore, it's essential to pair it with a very light color for text, such as white or a light yellow, or a much darker color for the background. Tools like contrast checkers can help ensure that the chosen color combinations meet accessibility standards, thus improving the user experience for everyone.
