The color #1D527B, also known as Chathams Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of approximately 0.1 means that it requires careful consideration when used as either a text or background color. To ensure sufficient contrast, it is crucial to pair this color with significantly lighter shades. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14 points bold or 18 points regular). When using #1D527B, developers should verify that these contrast ratios are met to ensure readability for all users, including those with low vision. Tools like contrast checkers can be invaluable in this process. For decorative elements or inactive interface components, the contrast requirements are less stringent but still important to consider. Also, avoid using it as the sole indicator for interactive elements, as colorblind users may not be able to differentiate them.
