The color #1C527B, also known as Chathams Blue, presents some accessibility challenges, particularly in text-based applications. Its relatively low lightness value (approximately 23%) means that it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #1C527B as a background color, it is crucial to select a foreground text color that provides sufficient contrast. White (#FFFFFF) or very light shades of gray are generally good choices. Conversely, using dark text colors on a #1C527B background could make the text difficult or impossible to read for many users. In graphical user interfaces, ensure that interactive elements using this color have clear visual cues beyond color alone, such as labels or borders, to cater to users who may have difficulty distinguishing colors. Always test color combinations with accessibility evaluation tools to verify compliance with accessibility standards.
