The color #1C527C, also known as Chathams Blue, presents some accessibility challenges. Its relatively low luminance value of approximately 0.14 means that it requires careful consideration when used as a foreground or background color. According to WCAG guidelines, it fails to meet the minimum contrast ratio of 4.5:1 for normal text against a white background. Therefore, using #1C527C for text requires a lighter color for readability. For instance, pairing it with white or a very light grey significantly improves readability. When used for larger text or UI elements, the contrast requirements are less strict (3:1), but it is still essential to ensure adequate contrast. Designers and developers should use color contrast tools to verify that the combination of #1C527C with other colors meets accessibility standards, thus ensuring usability for individuals with visual impairments.
