The color #18151C, also known as Vulcan, presents some accessibility challenges, primarily due to its low luminance. When used as a background color, sufficient contrast with text is crucial for readability.

It is advisable to use contrast checking tools to ensure compliance and consider providing alternative color schemes that offer higher contrast for users who need them. When #18151C is used for decorative elements, ensure it doesn't convey critical information that might be missed by some users.
