This color is frequently used in designs where a subdued and elegant atmosphere is desired.

Otherwise the user experience will be negatively affected.

The color #101325, also known as Vulcan, presents significant accessibility challenges due to its very dark nature. With extremely low luminance, it offers minimal contrast against most background colors, particularly white. According to WCAG guidelines, sufficient contrast is essential for readability and usability, especially for users with visual impairments. To ensure accessibility, it's crucial to pair Vulcan with very light colors that provide a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using Vulcan for large blocks of text or interface elements should be avoided unless careful consideration is given to the foreground color. Alternatives might include slightly lighter shades or the strategic use of outlines and shadows to improve legibility. Furthermore, providing alternative color schemes that offer better contrast is a best practice to accommodate a wider range of user needs and preferences. It is imperative to evaluate the color combination with accessibility testing tools to validate compliance with accessibility standards.
