The hex color #0A202A, also known as Firefly, presents some accessibility challenges, especially when used for text or important user interface elements. Its low luminance value of approximately 2% means that it requires a very light foreground color to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text. When using #0A202A as a background, foreground colors such as white (#FFFFFF) or very light shades of gray are recommended. Tools like contrast checkers can help determine if the color combination meets accessibility standards. Avoid pairing this dark color with other dark or muted colors, as this can lead to readability issues, particularly for users with visual impairments. Careful consideration of color choices is crucial to create inclusive and user-friendly designs.
