The hex color #0a2c28, also known as Firefly, presents considerable accessibility challenges, particularly in text-based applications. Its low lightness value of approximately 6% means that it requires a very light foreground color to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using white text (#FFFFFF) against #0a2c28 yields a contrast ratio that meets the minimum requirements, but careful consideration is still needed. For users with visual impairments, especially those with low vision, a slightly lighter shade than pure white may be preferable to reduce glare. When using this color for interactive elements, ensure that hover and focus states are clearly indicated with sufficient contrast. This color is not suitable for important UI elements that need to be highly visible.
