The hex color #0b2030, also known as Firefly, presents accessibility challenges due to its dark nature. When used as a background color, it requires very light text (ideally white or near-white) 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 to meet AA compliance. This color may not meet those guidelines with many colors. Therefore, it's crucial to test the color combination using accessibility tools to confirm compliance. When used for decorative elements, less contrast is needed, but usability should still be considered. If this color is used for interactive elements, make sure hover and active states have sufficient contrast. Visually impaired users may have difficulty distinguishing elements if contrast is insufficient. Providing alternative high-contrast themes can improve accessibility.
