The hex color #174A84, also known as Chathams Blue, presents some accessibility considerations for web design. Its relative luminance is low, meaning it may not provide sufficient contrast when used as text against a white background or other light colors. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #174A84, it's important to pair it with a significantly lighter color to meet these guidelines. Tools like contrast checkers can help evaluate the color combination's compliance. Additionally, avoid using this color alone to convey important information, as colorblind users might not be able to distinguish it. Always provide alternative cues like text labels or icons.
