The color #0A1F2D, also known as Firefly, presents some accessibility challenges, particularly concerning color contrast. When used as a background, it requires very light text colors to ensure readability for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as specified by WCAG guidelines. Therefore, pairing this dark shade with colors like white or very light yellows and greens is crucial. Avoid using it with darker shades or mid-tones, as this can make the text difficult to read. Careful consideration of font size and weight can also help improve readability. Testing with accessibility tools is highly recommended to ensure compliance with accessibility standards and provide an inclusive experience for all users.
