The hex color #0b2227, also known as Firefly, presents some accessibility challenges, primarily due to its dark nature. When used as a background color, it requires very light text to ensure sufficient contrast for readability.

A color like #0b2227 necessitates careful selection of foreground colors to meet these ratios. Using online contrast checkers can help web developers determine if the chosen text color provides adequate contrast. Moreover, avoid using this color for crucial interactive elements without thorough testing on different screens and for users with visual impairments. Consider providing alternative color schemes that offer higher contrast for users who may need them. Also think about using the focus indicator to ensure keyboard navigation will be clear and perceivable.
