The hex color #180E1B, also known as Vulcan, presents some accessibility challenges, especially when used for text or interactive elements. Its low luminance of 2.25 cd/m² and contrast ratio of 1.85:1 against a white background fail to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (4.5:1) or large text (3:1). Therefore, using #180E1B as a primary text color on a white or very light background is strongly discouraged. To improve accessibility, consider pairing it with much lighter colors to ensure sufficient contrast. For instance, using a light grey or off-white text on a #180E1B background can enhance readability. Additionally, avoid using this color for critical UI elements without proper contrast adjustments to ensure that users with visual impairments can perceive and interact with them effectively. Tools like contrast checkers can assist in verifying compliance with accessibility standards.
