Its rich depth lends itself to creating a sense of luxury and stability.

The hex color #2B100A, also known as Coffee Bean, presents significant accessibility challenges, especially when used as text against a white or light-colored background. Its low luminance results in very poor contrast ratios, often failing to meet WCAG (Web Content Accessibility Guidelines) AA or AAA standards. This can make content difficult or impossible to read for users with visual impairments, including those with low vision, color blindness, or cataracts. To improve accessibility, consider using #2B100A sparingly for purely decorative elements or pairing it with very light colors (e.g., shades of white or beige) to achieve sufficient contrast. Tools like contrast checkers can help evaluate the color combination and suggest adjustments for optimal readability. Avoid using this color for essential information, interactive elements, or links without carefully considering the contrast. Always prioritize inclusivity and ensure your website is usable by everyone.
