The hex color #0A282A, also known as Firefly, presents some accessibility challenges, particularly when used as a primary color for text or interactive elements. Its low luminance value of approximately 2.7% means that it falls far short of the WCAG (Web Content Accessibility Guidelines) recommended contrast ratios for normal text (4.5:1) and large text (3:1) against a white background. Therefore, using #0A282A for text on a white background would make it very difficult for users with visual impairments to read. To improve accessibility, it's essential to pair #0A282A with much lighter colors for text and interactive elements. Lighter shades of gray, or even white, would significantly improve the contrast ratio and make the content more accessible to a wider audience. Avoid using this color for critical interface elements without careful consideration of contrast.
