The hex color #11181E, also known as Vulcan, presents considerable accessibility challenges due to its low luminance. With such a dark shade, careful consideration must be given to contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text (14pt bold or 18pt regular) against its background. Using #11181E as a background color mandates the use of very light foreground colors to meet these standards. When using this color, ensure that sufficient color contrast is provided so that users with visual impairments, including those with low vision or color blindness, can perceive the content effectively. Tools are available online to check color contrast ratios, which should be used during the design process to validate compliance with accessibility standards. Also consider providing alternative ways to convey information other than color alone.
