The hex color #0a282e, also known as Firefly, presents significant accessibility challenges, particularly for users with visual impairments. Its low lightness value of approximately 6% means that it is very dark, leading to low contrast against most background colors. According to WCAG guidelines, sufficient contrast is essential for readability and usability. When used as text, #0a282e requires a light background color to meet the minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. A contrast checker tool is invaluable in determining compliant color pairings. For interactive elements like buttons or links, ensure a clear visual distinction using both color and additional indicators, such as underlines or borders, to accommodate users with color blindness. Furthermore, avoid using #0a282e as the sole indicator of focus or state, as this can exclude users who rely on visual cues to navigate.
