The color #172830, often called Firefly, presents some accessibility challenges, especially when used as a background or text color. Its low lightness value makes it difficult to achieve sufficient contrast with lighter text colors, potentially violating WCAG guidelines for color contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, when using #172830, it is crucial to pair it with very light colors like #FFFFFF or #F0F0F0 to ensure readability and accessibility for users with visual impairments. Avoid using it with mid-tone grays or darker colors as the contrast will likely be insufficient. Always test color combinations using accessibility tools to verify compliance with accessibility standards. Ensuring sufficient contrast is vital for users with low vision or color blindness.
