The hex color #0b222a, 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 the text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Using a color like #0b222a for crucial user interface elements or calls to action without careful consideration of contrast could exclude users with visual impairments. Therefore, pairing this dark color with a very light color such as white or a bright yellow is essential for optimal accessibility. When used with images or decorative elements, ensure the surrounding elements provide sufficient visual separation for users.
