The color #15252B, also known as Firefly, presents some accessibility challenges, especially concerning text and UI elements. Its low luminance value of approximately 3.8 cd/m² means it offers very little contrast against darker backgrounds, making it difficult for users with visual impairments to discern content. To ensure accessibility, it's crucial to use Firefly with lighter colors that provide a sufficient contrast ratio, ideally exceeding the WCAG recommended ratios of 4.5:1 for normal text and 3:1 for large text and UI components. When using Firefly as a background, avoid pairing it with dark text or intricate dark icons. Consider using it for large graphic elements or in combination with lighter overlays to maintain readability and visual clarity. Furthermore, avoid relying solely on color to convey important information, as colorblind users might not be able to distinguish Firefly from other similar dark hues. Always provide alternative cues like text labels or icons to reinforce the message.
