The color #12111A, also known as Vulcan, presents significant accessibility challenges, especially in text-based contexts. Its extremely low luminance results in very poor contrast against typical light-colored backgrounds, making it difficult for users with visual impairments to read text or distinguish interface elements. According to WCAG guidelines, it would fail most contrast ratio tests against white or light gray backgrounds. To improve accessibility, designers should pair Vulcan with very light colors, ideally whites or very pale yellows, greens, or blues, to ensure sufficient contrast. The use of larger font sizes and heavier font weights can also mitigate some of the legibility issues. Alternatively, avoid using this color for essential information and reserve it for decorative elements or backgrounds where legibility is not paramount. Using tools to simulate color blindness can help designers identify potential accessibility problems.
