The color #1C517C, also known as Chathams Blue, presents some accessibility challenges, especially when used for text or interactive elements. Its relatively low lightness value (approximately 21%) means that it requires careful consideration of contrast ratios to ensure readability and usability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) against the background. When using #1C517C, it is crucial to pair it with a light background color to meet these contrast requirements. For instance, white or very light shades of gray or yellow would provide sufficient contrast. Tools like contrast checkers can be used to verify compliance. Failure to meet these contrast ratios can result in content that is difficult or impossible for some users to perceive, leading to a poor user experience. Furthermore, when used for links or buttons, supplementary cues such as underlines or icons should be included to ensure that these elements are easily identifiable.
