The color #17161E, also known as Vulcan, presents significant accessibility challenges. Its low luminance value of approximately 3.2 cd/m² results in poor contrast against standard white backgrounds, failing WCAG (Web Content Accessibility Guidelines) AA and AAA standards for normal and large text. This means users with visual impairments, including those with low vision or color blindness, may struggle to distinguish text or interface elements using this color. To improve accessibility, consider using #17161E sparingly, especially for text or interactive components. Pair it with significantly lighter colors to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text to comply with WCAG AA standards. For AAA compliance, strive for contrast ratios of 7:1 and 4.5:1, respectively. Tools like online contrast checkers can help evaluate and adjust color combinations to meet these requirements.
