The hex color #181107, also known as Crowshead, presents significant accessibility challenges due to its very dark nature. Its low luminance value makes it unsuitable for text or interactive elements against a white or light background, as it fails to meet the contrast ratio requirements set by WCAG (Web Content Accessibility Guidelines). A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text or graphics. When using #181107, it is crucial to pair it with a very light color to ensure readability and usability for individuals with visual impairments. Otherwise, it risks excluding a portion of users, leading to a poor user experience. Consider using a color contrast checker tool to verify compliance with accessibility standards before implementation.
