The color #102D35, also known as Firefly, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value (relative darkness) results in poor contrast against typical light backgrounds, making text and graphical elements difficult to perceive. Web developers should avoid using this color for essential content or interactive elements without ensuring a high contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Using color contrast analyzers is crucial to verify compliance with WCAG (Web Content Accessibility Guidelines) standards. Pairing #102D35 with much lighter colors, such as whites, yellows, or light greens, can improve readability. Additionally, consider providing alternative cues like icons or text labels for users who cannot distinguish color differences effectively. Thorough testing with assistive technologies is also recommended to ensure usability for all users.
