The color #151123, also known as Vulcan, presents significant accessibility challenges due to its low luminance. Its dark nature results in a poor contrast ratio against standard white backgrounds, making it difficult for users with visual impairments to read text or distinguish elements. Web developers should avoid using this color for text or interactive components unless paired with a very light or contrasting color. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to comply with WCAG guidelines.

Using tools to check contrast ratios can help determine whether the color combinations meet accessibility standards.
