The color #174E84, also known as Chathams Blue, presents some accessibility challenges, especially when used as a foreground color on a white or light background. Its relatively low luminance requires careful consideration of color contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #174E84 for text, it's crucial to pair it with a very light color like white or a pale yellow to meet these contrast requirements. If used for interactive elements like buttons or links, hover and focus states should also be designed with sufficient contrast to provide clear visual cues for users navigating with keyboards or other assistive technologies. Furthermore, avoid using this color alone to convey important information; always supplement color with text labels or icons to ensure information is accessible to all users, including those with color blindness.
