The color #0B212A, also known as Firefly, presents some accessibility challenges due to its dark nature. When used as a background color, it requires very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Firefly's darkness might not meet these ratios with moderately light colors, making it crucial to carefully choose text colors. Designers should use contrast checking tools to verify compliance. For users with visual impairments, providing options to switch to a high-contrast theme is advisable when using Firefly in web design. When using Firefly, ensure all interactive elements have sufficient contrast and hover states have clear visual distinctions.
